  1. 1
    investmentnouncountable
    A document recording a long-term debt that obligates the issuer to pay interest when due and to repay the principal at maturity.

    Investors bought the ten-year bond expecting steady interest payments.

    The city issued bonds to finance the new bridge.

    UsageOften named by issuer: government bonds, corporate bonds. A borrower issues them and investors buy and hold them.

    Note

    The investor's bond turns a loan into something that can be bought and held. The issuer is the borrower and the holder is the lender. What the holder may claim is often set out in a separate legal document, the indenture, and not on the certificate alone. Bonds have long come in two forms, registered and bearer, though bearer bonds are now rare.

    Note

    In legal talk and news reports, "bail bond" is often cut to a single word. The verbs that go with it are post and forfeit: once the bond is posted the prisoner is released, and a defendant who runs forfeits it. Someone released this way is "out on bond," the phrase Victoria Bekiempis uses of Ellison in 2023. The matching verb belongs to the same courtroom vocabulary.

Origins

Meanings 1–2, 4, 6–9, 12, 14–15, 17–19, 23

Proto-Germanic *bandaz/*bandiz lies behind Old English 'beand'/'bænd'/'bend' (bond, chain, fetter, band), which gave Middle English 'bond', a variant form of 'band'. Dutch, German, and Swedish 'band' are cognates, and 'bind' is related.

Meanings 16, 24

Proto-Germanic *būwandz (dweller) is the ultimate source, perhaps by way of Old Norse 'bóndi' (householder, literally 'dweller') or else through a contraction of Old English 'būend' (dweller); it gave Old English 'bōnda'/'būnda' (householder, freeman), which became Middle English 'bonde' (peasant, servant, bondman).
