(arylamino)
amino on an aryl ring
Etymology
'aryl-amino' originates from modern chemical combining forms 'aryl' and 'amino', where 'aryl' comes from the chemical combining form derived from 'arene' plus the suffix '-yl' meaning 'radical/substituent', and 'amino' comes from 'amine' (from Neo-Latin) referring to an ammonia-derived nitrogen group.
'aryl-amino' developed in 19th-century organic chemistry by joining the established combining form 'aryl' with 'amino'; over time the term has appeared hyphenated as 'aryl-amino' and unhyphenated as 'arylamino' in systematic and informal usage.
Initially the elements 'aryl' and 'amino' referred separately to an aromatic radical and an ammonia-derived group; over time the combined form came to denote specifically an amino group bonded to an aryl ring or compounds bearing that feature.
