'amino-related' is formed from the word 'amino' (from Latin 'ammoniacus', relating to ammonia) and the suffix '-related', meaning 'connected to'.

The term 'amino' was adopted in the 19th century in chemistry, and 'related' is from Middle English 'relaten', from Latin 'relatus'. The compound adjective 'amino-related' emerged in modern scientific English.

Initially, 'amino' referred specifically to ammonia derivatives, but in modern usage, 'amino-related' broadly refers to anything associated with amino groups or amino acids.
