'misphrase' originates from English, specifically formed from the prefix 'mis-' (Old English 'mis-') meaning 'wrong' and 'phrase', which ultimately comes from Greek 'phrasis' meaning 'speech' (via Latin/Old French).

'misphrase' developed by combining the negative prefix 'mis-' with the English word 'phrase' (itself from Greek 'phrasis' through Latin/Old French), and became the modern English verb 'misphrase' with past/past-participle 'misphrased'.

Initially, 'phrase' referred to 'speech' or a way of speaking; over time it came to mean 'a group or arrangement of words'. Adding 'mis-' shifted the sense to 'to express wrongly', which is the current meaning of 'misphrase' and its forms like 'misphrased'.
