How is the word field derived from the Latin word ager? The word agriculture, yes, but I don’t see how field comes from ager.
BTW -
“ The origin of the term ‘field day’ comes from the military and refers to maneuvers that took place in a field, but by the 1800s, the phrase was used to refer to any event that happened in a field, ranging from a hunt to a dance to a picnic to a scientific expedition.”
practicum is Latin
field is Germanic
