Lego® Acronym Helper

Welcome to the Lego Acronym Helper. Here you will find a list of common acronyms used by Lego fans.

Like all specialty fields, Lego collecting has a language all its own. Sometimes an acronym is mentioned in full elsewhere within the work: like a set name abreviated rather than repeated over and over. Most acronyms with LUG or LTC are Lego User Groups or Lego Train Clubs. Some acronyms are not Lego specific, and appear in other acronym lists. But there are still those acronyms used so often, that the experienced reader understands, and the newly inspired builders are confused. That is why this list was built.

Credit goes to Derek Schin's rtlspeak and Shiri Doris's The Lego Acronym FAQ for earlier incarnations of this list. And thanks to the many contributors to this list over the years. Frequently just asking, either on the LUGNET Forums or on your favorite board will get a reply. If you see an Lego acronym that should appear here, please Contact Clark!
