The Spanish word 'agrimensor' (meaning 'land surveyor') comes directly from the Latin word of the same spelling and meaning. The Latin 'agrimensor' was formed by combining two elements: 'ager' meaning 'field' and 'metior' meaning 'to measure'. This compound literally described someone who measures fields, which evolved into the professional title for a land surveyor.

Some related Spanish words include 'agricultura' (agriculture) and 'agrícola' (agricultural), which also contain the Latin root 'ager' (field). The measuring component 'metior' is related to Spanish words like 'medir' (to measure) and 'medida' (measurement).

English speakers might recognize the 'agri-' element in words like 'agriculture', 'agrarian', and 'agribusiness', all relating to fields or farming. The measuring element appears in English words like 'measure', 'measurement', and 'immense' (originally meaning 'unmeasurable').
