noun
making a servant one's mistress; mistress who is a servant
Dated term for taking a female servant as a mistress, or the mistress herself. Rare in modern usage.
江戸時代の文献には、お手つきという言葉が女中を妾にする意味で出てくる。
In Edo-period documents, the word お手つき appears with the meaning of making a maid one's mistress.
Without the honorific お, 手つき means 'the way one uses one's hands' or 'hand movement', not a foul or mistress.
From お (honorific prefix) + 手つき (touching with the hand). The karuta sense derives from the action of touching a card; the dated mistress sense is an extension of 'hand' implying possession or handling.
