The Spanish word 'ejidatario' refers to a member of an ejido (a communal farming land). It comes from combining 'ejido' with the suffix '-ario' meaning 'person related to'. The word 'ejido' itself has interesting Latin roots - it comes from the Latin 'exitus' meaning 'exit' or 'departure', which was formed from the prefix 'ex-' (meaning 'out') and the verb 'ire' (meaning 'to go'). Over time, the meaning evolved from referring to a way out or exit to specifically meaning the common lands at the exit or outskirts of a town, which eventually became the modern Mexican system of communal land holdings called ejidos.

Some related simpler Spanish words include 'éxito' (success) and 'salida' (exit), which share the same Latin root 'exitus'. While 'ejido' came to refer to communal land at the outskirts of town, 'éxito' developed from the idea of 'outcome' or 'result' to mean 'success', and 'salida' maintained the original meaning of 'exit' or 'way out'.

English speakers might recognize the connection to words like 'exit' and 'exitous', which come from the same Latin root 'exitus'. The English suffix '-ary' (as in 'secretary' or 'beneficiary') is also related to the Spanish suffix '-ario', both coming from Latin '-arius' and referring to a person connected with something. This parallel can help English speakers understand how 'ejidatario' means 'a person connected with an ejido'.
