Creditor
“Neither a borrower nor a lender be,
For loan oft loses both itself and friend,
And borrowing dulls the edge of husbandry.”
- —Hamlet, I, iii
Literally — for creditor comes from the Latin credo, credere, credidi, creditum — a believer. One who extends credit, which one might do deliberately by lending money, and inadvertently if one’s at-the-money transaction improves in value, such that the poor fellow owes you money.
