'apedom' originates from English, formed by combining 'ape' and the suffix '-dom', where 'ape' meant 'ape' and '-dom' meant 'state or condition'.

'ape' comes from Old English 'apa', and the suffix '-dom' comes from Old English '-dom' meaning 'state, condition'; these elements combined in modern English to form 'apedom' (a relatively modern coinage).

Initially it would literally mean 'the state of being an ape', but over time it has been used figuratively to mean 'ape-like behaviour' or 'apish mimicry'.
