The earliest form of the word Hello is hallow, which can be traced back to Chaucer (1340- 1400). This is a common greeting at that time, and the stress falls on the last syllable. In Shakespeare's time, hallow evolved into halloo. Since then, sailors and hunters often use halloo, halloa, hollo, etc. as appellations, among which halloo is still used by fox hunters. With the passage of time, hallo and halloa eventually evolved into hullo. Some British people prefer this form, while Americans generally use hello.
