the wife; the missus
Casual, somewhat rough way for a husband to refer to his own wife. Often used among close friends or in informal settings. Can sound affectionate or mildly dismissive depending on tone.
The wife went shopping again.
Sorry, my wife is being noisy.
Kanji spelling using 奴 for やつ; the expression is usually written in kana.
Variant using 内 for うち; less common and may be confused with other readings.
Mixed kanji-kana spelling; rare in practice.
Phrase composed of うち (one's own home/family) + の (possessive particle) + やつ (informal term for a person). The combination literally means 'the person of my house' and is used as a casual, familiar way to refer to one's wife.
