forme

Synonym discussion
Sense: noun/1
All three terms relate to letterpress printing but differ in scope. 'Forme' (British spelling) refers to the complete assembly: a metal chase (frame) that holds the blocks of type locked in position, ready for the press. 'Chase' is narrower — it names only the metal frame itself, not the type inside it. 'Type form' is the American spelling of the same object and is used interchangeably with 'forme' in US printing manuals. In practice, a printer would say 'lock up the forme' (meaning the whole assembly) but 'remove the chase from the press' if talking about just the frame. For a learner of English encountering traditional printing terminology, 'forme' is the most comprehensive term to know.

Etymology
The word 'forme' was adopted from French 'forme', meaning 'shape' or 'arrangement', which itself came from Latin 'forma' ('form, shape, mold'). The printing sense developed in the 1500s when movable type was first assembled into pages. The spelling with a final 'e' (forme) became standard in British English for the printing meaning to distinguish it from the more general word 'form', though American English uses 'form' for both.
