Cuckoldry: meaning

Also: cuckoldries, cuckoldy

Cuckoldry is the abstract noun for everything in the cuckold family: the state, the fact, the shame, the joke. It has a long life in English, in zoology and in jokes about marriage, and only part of it overlaps with the kink.

The historical sense

In medieval and early modern English, cuckoldry was a social fear. A man whose wife was unfaithful was marked, according to the jokes, by invisible horns. Plays and ballads mocked the husband and the lover alike, and a man could be teased in the street. The word carries that baggage of public shame, which is why the kink version often plays on it: a husband who chooses what he used to dread.

The biological sense

Biologists use "cuckoldry" for male animals that unknowingly raise offspring sired by another male. The word is a loose borrowing from the cuckoo, a bird that lays its eggs in other birds' nests so that the foster parents raise its chick. The two cases are not exactly the same, but the image stuck.

• Extra-pair paternity is the technical term for young fathered by a male outside the pair bond. In many bird species it is common.
• Mate guarding, the behaviour of watching a partner closely, is one evolved response. See mate guarding.
• Sperm competition is another, covered in Sperm Competition and Cuckolding.

None of this predicts what any couple does. It explains why jealousy has deep roots, and why a safely controlled version can feel so strong.

Cuckoldry vs cuckolding

Cuckolding in the lifestyle sense is an agreed practice. Cuckoldry in the old sense is something that happened to a man. A man who is a "cuckold" in one is a participant in the other.

Using the words correctly

• "Her cuckoldry of him" is odd; say "her cuckolding of him."
• "The cuckoldry of the farmer in the tale" is fine for the historical sense.
• In an ethical non-monogamy setting, avoid "cuckoldry" for anything consensual unless you wish to sound academic.

Why the old shame matters to the kink

Many men find the history exciting rather than off-putting. The taboo that society used to enforce is exactly what gives the fantasy its charge. This is also why Cuckold Fantasy vs Reality is worth a read: a feeling that depends on shame may not survive being turned into daily life.

In my own voice

I am a wife, and a Queen of Spades, speaking as a fantasy persona. When I tell you, in audio, that the husband in the story is allowed to know, I am offering a modern answer to the old fear: no secrets, no horns, no joke at his expense. Start Here is the place to hear it, and Part 1: The Ring Stays On is the quietest way in. For the long view, History of the Word Cuckold traces how a bird's habits became a marriage metaphor.
