'bachelordom' originates from English, specifically a combination of 'bachelor' and the Old English element 'dōm', where 'dōm' meant 'state, condition' and 'bachelor' came via Old French 'bacheler' (Medieval Latin 'baccalarius') meaning 'young man, novice'.

'bachelordom' changed from Middle English forms such as 'bachelerdom' or 'bachelordome' and eventually became the modern English word 'bachelordom'.

Initially connected to the idea of the 'state of a young man or novice', the term evolved to specifically denote the 'state of being an unmarried man' (bachelorhood).
