An archaic or obsolete term for someone who encounters or meets another; one who faces or confronts.
From Old French encontrer, from Latin contra (against) plus the agentive suffix -er. Related to 'encounter,' this term fell out of use as 'encounter' became the standard form.
This is basically an ancient English word for 'someone you bump into'—it's similar to how 'reader' means 'someone who reads,' but nobody says 'acounter' anymore because 'encounter' took over the meaning.
