Capitulate is formed from "capitulum" (meaning a small head or chapter) and the suffix "-ate" (indicating to make or to do). The word originally referred to the act of drawing up terms or conditions, akin to presenting a 'head' or summary of terms in a negotiation, thus meaning to surrender or give up under agreed terms.
Think of 'capitulum' as a 'head' of terms being presented — when someone capitulates, they are summarizing their terms of surrender.
