Latin capitale (property, from caput, head, wealth counted in heads): Norman French first brought it as cattle/chattel (movable property, i.e., livestock), then medieval Latin re-imported it as capital (wealth, funds). Doublets from one root: also chief/chef, ward/guard. The head-counting of wealth is the shared skeleton.
The summary everyone makes: for most of human history, your herd was your net worth, and law, war, and marriage were cattle transactions. Bridewealth, stampede, and stock (livestock, stock market) kept the barn in the boardroom.
Cattle closes the circle with capital and fee: three English words for money, all built from livestock anatomy, head or herd. PIE *peku and *kaput kept separate ledgers, but the account was the same: before coins, wealth breathed, and the language still feeds it.
When English borrowed the same word twice, what was it buying each time?
