Phono-semantic matching (PSM) is the incorporation of a word into one language from another, often creating a neologism, where the word's non-native quality is hidden by replacing it with phonetically and semantically similar words or roots from the adopting language. Thus the approximate sound and meaning of the original expression in the source language are preserved, though the new expression (the PSM – the phono-semantic match) in the target language may sound native.

Phono-semantic matching is distinct from calquing, which includes (semantic) translation but does not include phonetic matching (i.e., retention of the approximate sound of the borrowed word through matching it with a similar-sounding pre-existent word or morpheme in the target language).

Phono-semantic matching is also distinct from homophonic translation, which retains the sound of a word but not the meaning.
