Want to learn to speak LEGO fluently like a true AFOL? Here is a detailed LEGO Glossary containing Terms and Acronyms often used in the LEGO hobby. Learn to use them, so if you end up going to a wonderful LEGO convention you won’t feel like a stranger in a strange land, listening to a strange language! Also make sure you check out the BASIC TERMS section! And if I’m missing something from the list let me know and I will ad it! 🙂

Some things I thought about as I am reading it (I’m not done yet) are that FFOL is often for Female Fan of LEGO; that’s the term they use for the FFOL group on flickr. Also, CC can also mean Cafe Corner; you really have to use context to figure out which is meant. 😉
Thanks, Katie, I added both. That’s too funny though! Female fans have 4 acronyms, versus everybody else. I guess gals always have to be complicated! 😀
Okay, nice! 😉
Interesting! I read some of these terms before on forums but didn’t know what they meant! Thanks! 😀
Thanks for posting this! Very helpful! Yeah, Lego fans definitely have their own language! 😀
Great post! Thanks for sharing! BTW, I love the Beginners Guide section! Lots of stuff I didn’t know about! Good to get up to date so to speak!
Nice! Getting Myself educated here so I don’t look dumb on lego forums! LOL! 😀
i found this guide while looking for another one 🙂 this one is good and i liked it to my FB, but i was hoping for a sort of technical glossary for on-line PAB. ie: you might think it’s a grey steering wheel, but it’s actually a 1 x 2 x 3 podium with weather vane (just kiddin on the ‘real’ description) but you know, a what’s-this doodad-called type glossary. it’s very hard for me to find specialized bricks in PAB.
Sean, excellent idea! So, it could be like a glossary with online PAB terms = Bricklink terms = and layman terms. Is that right? It would be some work to put it together, but could be done. I know what you mean by finding things in the online PAB! I’m always surprized of how they categorize and name some parts! 😆
Actually, now that I think about it, the same thing could be done with colors. PAB colors and Bricklink colors do not match, nor is it always obvious what they mean in layman terms. I put both ideas on my to-do list, and of course if you want, you can write them too! 😉
Another version for KFOL is YFOL (Young Fan Of Lego), And I’ve heard of it more than KFOL. And there’s the new Microfigs from the Games.
Thanks, Quad, I will add them to the dictionary! 🙂
Nice job! You’re missing DS(dreaded sticker sheet) though.
LOL! That is just too funny! I haven’t heard it before! I’m gonna add it right now! 😆
Man , I hate clone brands!!!!! Y cant losers get their own ideas! Specialy the ones that look like lego!!! Reply If you ever found a copycat brand and almost bought it(till u saw the name) I use lego digital designer to see if parts legally fit (but I call it legolley!) Here’s
My list of lego vocab! Legolley – legally. Bricking – building. Bricky CHRISTmas – You got bricks for Christmas. Knock-off bricks- STUPID FAKE BRANDS! Im done bricking- I gota go to the bathroom , be back in 5! lol!
Hi. I love this, it’s great. I’m a VERY proud fafol. And a purist. I pity nlp. I have some moc in my beautiful town that consists of cc, grande emperium (is that GE?), fire station, pet shop etc. my moc’s are a bike shop, bakers, florist, Italian cafe and I’ve extended market street. I found this while looking for names for the roads in my town. One will be brick avenue but I need two more names. Any suggestions? I live in a place called west bridgford and my town is called west brickford.
Thanks for the entertainment!
Justine, welcome to our little corner of the LEGO universe! Would love to see photos of your LEGO town! Well, if you have the Market Street set, you could call a whole street after that. Other than that I would probably go thru the BrickLink catalog for names of LEGO sets and parts until something clicks. 😉
Thank you. And thank you for the tips for street names. I will get round to taking some photos and send them to you.
Justine, that sounds good! Looking forward to them! 🙂
Here is some of my vocab-
Legolley – legally , no stress to bricks
Magnafig- minifigure from a magnet set
KRM- Keychain-removed minifig
Bricktographey-professional lego pictures
Brick-made- A regular picture or structure (exmpl , family photo , statue of liberty) remade into lego form
Retired-when a lego brick or minifig get loose or damaged so you put it away
Un-Clean Creation-A creation that uses legos and or copy-cat brands
WPB- A lego build or set that can float on water
I will have more soon if I can.
Tobymacboy, thanks for sharing! 😉
The brick stress rules must be relatively new. Some of the 1980s sets and Idea Books include official instructions which cause severe brick stress (and actually broke a brick on me once).
Nathanael, yes the brick-stress rules are fairly new. For example, wedging a plate in between studs used to be pretty common. Now it is no longer allowed for designers to use. I have run into a stress-problem just in the past couple weeks though. But I don’t think it has to with technique, but more like a defective part. But yeah, LEGO has to keep testing and retesting parts to make sure they fit right. Especially with all the new parts they are producing. 🙂
WPB means water proof build
BOOB = Brick Out Of Bricks, POOP = Piece Out Of Pieces.
Both mean the same thing. One example is using three 2×4 plates directly stacked on top of one another to form a 2×4 brick (Hey! you have SNOT!! So don’t say BOOB and POOP are “dirty” words!!)
Brian, thanks for contributing! Please note that the terms currently included in the Dictionary are widely used in the AFOL community. I have not heard either of the terms you mentioned before. They are fun, but unless I see it used by AFOLs around I won’t be able to add them to the Dictionary. Let me know which AFOL communities are using the terms and I will consider adding them. 😉
I do not remember when or where I heard these terms, since they are very very seldom used. Feel free to delete this chain of comments.
Brian, discussions and suggestions are perfectly all-right. It may even start making a term popular as other members read them. 😉
Really helpful. Can use these on lego forums!
I see you haven’t added NON! 😉 U know what that stands for?
Never heard of that one being used in the LEGO community. 😕
I am coordinating a TEAM BUILD event during our Employee Appreciation Week in September. We are going to use a Lego theme and have the different departments build a model that best represents our line of business. Can you assist me in coming up with a Team Build Theme using the word LEGO. My son is a brick master club member so I have him helping his mom come up with a catchy theme as well, but we are both stuck.
Thanks for your help!
Kat, so sorry for not responding earlier; I have been out of town for a few days. What is your business about? 😉
I think you should add the term “impulse (set)”, the small sets sold to give a feel to a theme or special new parts or minifigs. It’s not self-explanatory.
That is actually a great idea. I will add that! Thanks for the suggestions! 😉
I have a page that is similar to this on my site. See it here: http://brickextra.com/how-tos/lego-abbreviations/
What does MOTD mean?
Not sure. Never heard it mentioned amongst LEGO fans. 😕
I just found out that MOTD means MOC Of The Day!
Hm… never heard that before. I guess for someone who does MOCs daily it would make sense. Or for blogs who feature a new MOC every day. Maybe we should do a section like that too. Thanks for sharing! 🙂
Whats a greebles ship mean? I saw it on mocpages.
Greebles in LEGO terms usually refer to added details and decorations – especially in machinery, robots, space-ships, steampunk and other creations. They serve no structural function besides making the MOC looking really cool and detailed. 🙂
How about steampunk?
and LDD (lego digital designer)
you forgot BOLOCS!(Built out of lots of colors)
Hm… never heard of that one. Which LEGO community uses it? 😕
RIP, Rest In Progress 😉
Actually I was reading an article where someone asked the Lego groupbwhat the plural for the word Lego was and they said it was an adjective so it should always be followed by something else. Lego products, Lego toys, Lego Starwars etc. 😉 I didn’t know either for a while. And again that was straight from the Lego group.
Yep, that is actually correct. If you want to be super technical. But hardly anybody speaks or writes like that, including LEGO employees. In their broshures, books and other materials yes, but not in everyday language. I follow their rules as much as capitalizing the word LEGO and never using LEGOs, but I do use LEGO as the plural at times without anything following it, even though it is technically still not correct. I guess both the Grammar Police and the the LEGO Secret Service are after me. 😈
Nothing wrong with that. I am what some people would call a grammar freak though mainly because I cannot stand bad grammar and things like that. I suppose it doesn’t really show seeing as I made a misspelling in that comment above :p
Strider, I appreciate your endeavor. I actually like grammar myself, and I like languages. It is a fascinating subject about human expression, and also the way you can play with language and grammar (see poetry). It’s actually funny that we are talking about this as I’m planning to write a post about the proper use of the word LEGO. It is already on my to-do list. 😉
Sounds great 🙂
What is the acronym for a MOC that covers all studs with tiles or other elements such that there are no visible “LEGO” studs? I heard it once, but have forgotten it.
Daniel, I have to think about that. I know I have heard it too, but I can’t remember. There is SNOT, but that’s not exactly what you are describing. If I remember I will let you know. 😉
Is it a MD, Mosaic Diorama?
I picked up a couple thousand pounds of legos and manuals
I have been sorting by color and shape
Have boxes of manuals
The dedicated space is 30×20 room for me 5 and 10 year old (ok me to:)!
All my friends are amazed when they see it,
Anyway my question involves decoding part #
There are a lot of very Old sets I want to stay true as I can in
For example a simple gray dynamite tile the number is
3059 can see what set they came in
But also it reads as this
307 this #?
24 this # ?
I have looked everywhere online for some kind of
Decoder with no luck
Is there a simple thing I’m overlooking on these other#
Tanks for any help!!’
Shane, awesome loot you got there! As far as the part numbers, I highly recommend you ask these kind of questions at the Bricklink Forum. There are quite a few old LEGO fans there who are very knowledgable about this stuff. I know they will help you out. There are many people who attempt to lovingly restore old sets with elements made in that era. Here is the link to the Forum: http://www.bricklink.com/messageList.asp
Very educational. Thanks
Thanks for the info..
It is time to add micro scale and GBC (great ball contraption) to your list
Good ones! 😀
Fascinating! I came here because I didn’t know what BURPs were….I didn’t realize there were this many unique Lego terms!
I came here to find out what MOC and MOD meant. I figured MOD was some sort of modification, but could not figure out MOC. Thanks for helping with one. Might you want to add the other?
Mark, on LEGO forums mod is usually a shorthand for the “moderator” of the discussion, or it may also be a short for “modification”. Like a MOC would be a completely original creation, and a mod would be a modification of an official LEGO set. Mod also sometimes refers to “model”, but I don’t see this as often. However I have never seen mod capitalized as it is not an acronym like MOC, but a shorthand for a longer word.
As using mod for moderator, modification and model is not specific to the LEGO fan community, I probably won’t add it to the dictionary, however I will leave our discussion here, so others may benefit from it as well. 🙂
anyone know what the round piece with one stud is called?
Roxy, it depends. If it is a 1×1 round piece, then it would be a round plate. If it is a 2×2 round piece with one stud in the middle, it would be a round tile. 🙂
Question what do you call it if someone modifies an official LEGO set or an officialLEGO combination model
