compile v.

word-forming element usually meaning "with, together," from Latin com, archaic form of classical Latin cum "together, together with, in combination," from PIE *kom- "beside, near, by, with" (compare Old English ge-, German ge-). The prefix in Latin sometimes was used as an intensive.

Before vowels and aspirates, it is reduced to co-; before -g-, it is assimilated to cog- or con-; before -l-, assimilated to col-; before -r-, assimilated to cor-; before -c-, -d-, -j-, -n-, -q-, -s-, -t-, and -v-, it is assimilated to con-, which was so frequent that it often was used as the normal form.

mid-15c., "that which is compiled," also "action of compiling, act of bringing together and adapting things said or written by different persons for the exposition of a subject," from Old French compilacion "compilation, collection," from Latin compilationem (nominative compilatio) "a compilation," literally "a pillaging," noun of action from past-participle stem of compilare (see compile).

mid-14c., "a chronicler, one who makes a compilation," from Anglo-French compilour, Old French compileur "author, chronicler," from Latin compilatorem, agent noun from compilare (see compile). Another form of the word current in Middle and early Modern English was compilator "a plagiarist; a compiler" (c. 1400), directly from Latin.
