Etymology: A keyholder is simply the person who holds the key, and the word is a plain compound: "key" joined to "holder." The first part, "key," descends from Old English "cǣġ," which goes back to a Germanic root meaning something like a pin or peg, reflecting the early form of the lock-opening device. The second part, "holder," comes from the verb "hold," from Old English "healdan," combined with the agent suffix "-er," which passed through Middle English "-ere" and carries the sense of one who does the holding. Because both elements are native English material with ancient Germanic roots, the compound has no Latin or French detour, and its meaning follows directly from the parts. The word is transparent in a way many English compounds are not: anyone who knows what a key is and what it means to hold something can work out the whole word unaided.
