## AI Etymology
Fifo is an acronym formed from the initials of the phrase 'first in, first out,' coined in twentieth-century computing, accounting, and logistics. The etymological value lies in the continuity between the older named form and the modern English word, even where no further internal segmentation is supplied. In present use, it is used as a noun meaning "first in, first out: a method of ordering or processing items by arrival", so the historical material remains connected with the current sense rather than standing as bare ancestry. Contrasts such as lifo locate the modern specialization without adding a new origin story.
