Etymology
The word 'arbiter' originates from Latin, where 'arbiter' meant a judge, umpire, or eyewitness. It is composed of 'ar-' (a form of 'ad-', meaning 'to') and '-biter' (from 'baetere', meaning 'to go or come'). Thus, the literal sense is 'one who goes to (a place or situation)', specifically to observe, witness, and hence to judge. This evolved from the concrete idea of a person who is present to give a firsthand account into the abstract meaning of one who has the authoritative power to make final decisions or settle disputes.
Analysis
- ar- (Latin prefix): variant of 'ad-', meaning 'to, towards'. - bit (Latin root): from 'baetere', a variant of 'batre' (to go, to come). - -er (Latin suffix): agent noun suffix, meaning 'one who does'.
