preposition
against
uh-GENST/əˈɡenst/
In resistance or opposition to something.
Each player pulls against the other's force in the tug-of-war.

Etymology
On and gegn formed a word meaning both “toward” and “opposite, contrary to.” Against preserves its opposition sense, whereas the related again became associated chiefly with return and repetition.
