'anginoid' originates from the combination of the word 'angina' and the suffix '-oid', where 'angina' refers to a medical condition involving chest pain and '-oid' means 'resembling or like'.

'anginoid' was formed in modern English by combining 'angina' (from Latin) and '-oid' (from Greek), and eventually became the modern English word 'anginoid'.

Initially, it meant 'resembling angina', and this meaning has remained the same in modern usage.
