waifu (English)

Where does "waifu" come from?

The English noun 'waifu' was borrowed from Japanese 'ワイフ', which itself derives from the English word 'wife'[1]. The native English term traces back through Middle English 'wyf' and Old English 'wīf' meaning 'woman, wife'[2], originating from Proto-West Germanic '*wīb' and Proto-Germanic '*wībą' meaning 'woman; wife'[2][6]. Beyond Germanic, the earlier history of the root remains unknown[2]. As a doublet of 'wife', the modern term specifically denotes a fictional character to whom one is romantically attached.
