'non-amino' originates from English, combining the prefix 'non-' from Latin 'nōn' meaning 'not' with the combining form 'amino' from 'amine,' which ultimately derives from New Latin 'ammonia' (from Greek 'Ammon').

'non-amino' changed from the Latin/French elements 'non' and the French/New Latin chemical term 'amine' (via 'ammonia') into the English combining form 'amino-,' and eventually became the modern English scientific compound 'non-amino'.

Initially, 'non-' meant 'not' and 'amino' referred to compounds containing an amino group; over time their combination stabilized with the current meaning of 'lacking an amino group' or 'not related to amino compounds'.
