Definition
回信 (huí xìn) specifically means 'to reply by letter' or 'a reply letter' — it is used for written correspondence only. This distinguishes it from the general verbs 回答 (huí dá) and 回复 (huí fù), which can be used for any kind of reply (spoken, written, etc.). As a noun, it takes the measure word 封.
