"to collect and present information from authentic sources, to make or form by putting together in some order written or printed material from various sources," early 14c., from Old French compiler "compile, collect" (13c.) and directly from a Medieval Latin special use of Latin compilare "to plunder, rob," probably originally "bundle together, heap up;" hence "to pack up and carry off," from com "with, together" (see com-) + pilare "to compress, ram down." Related: Compiled; compiling.
