'paraeducator' originates from a combination of elements: the prefix 'para-' originates from Greek, specifically the word 'para', where it meant 'beside' or 'alongside'; and 'educator' originates from Latin, specifically the verb 'educare', where 'educare' meant 'to bring up' or 'rear'.

'paraeducator' developed in modern English in the mid-20th century by combining the prefix 'para-' (as in 'paraprofessional') with 'educator'; the term grew in usage in educational contexts in the United States to name staff who work alongside certified teachers.

Initially the prefix 'para-' conveyed the general sense of 'beside' or 'alongside' a professional; over time the compounded term 'paraeducator' has come to specifically mean 'an educational assistant who works alongside a teacher,' often with instructional or specialized support duties.
