across
UK: əˈkrɒs | US: əˈkrɔːs
prep. from one side to the other of something
prep. on the opposite side of something
adv. from one side to another
The word "across" originates from Middle English a-croiz, derived from Old French a croiz ("in the form of a cross"). The prefix a- (from Old English on) signifies position or direction, while cross traces back to Latin crux ("cross"). The term evolved to denote movement or position from one side to another, reflecting the intersecting lines of a cross. This vivid imagery helps learners associate the word with traversal or opposition.
