What does complier mean?
A complier is a person who compiles — that is, someone who gathers dispersed material such as documents, quotations, statistics, songs, or entries and arranges them into a unified whole. The word carries a connotation of patient, meticulous labor rather than original authorship: the complier's achievement lies in selection, organization, and accuracy rather than invention. It appears most often in formal or historical contexts, describing figures like the compliers of medieval manuscripts, encyclopedias, statistical yearbooks, or anthologies of folklore. In everyday modern English the near-synonym 'compiler' has largely displaced it, so 'complier' now reads as slightly literary or old-fashioned, and it is frequently confused in print with both 'compiler' and 'complier' in the sense of one who complies. Its rarity makes precision worthwhile when using it.
One who compiles; a person who gathers and arranges texts, data, or other material into a collection.

Before computers had compilers, a complier was simply a patient person with a stack of other people's work and a very good filing system.

Etymology of complier
The word derives from the verb 'compile', which entered English in the Middle Ages from Old French 'compiler', itself from Latin 'compilare', meaning to plunder, pillage, or snatch together — a vivid origin reflecting how early compilers gathered the writings of others into new works. The agent suffix '-er' simply marks 'one who does', producing a noun parallel to formations like 'writer' or 'reader'. Related forms sharing the same Latin root include 'compilation' and the adjective 'compilatory'. A separate, much rarer sense — one who complies — arises independently by analogy with 'comply'.
How complier is actually used
The word is somewhat formal and relatively rare compared with its synonym 'compiler', which dominates modern usage for both people and software. When clarity matters, writers often prefer 'compiler' or a more specific term such as 'editor' or 'anthologist'.
