haw has the recorded history: The fruit sense is from Old English haga ('hawthorn fruit, hedge enclosure'). The hesitation sense is imitative, representing the drawling sound of indecision, as in 'hem and haw'. The history explains the modern form through the named earlier word or formation, without requiring a separate speculative ancestry. The etymology remains cautious where the history is cautious: comparisons, echoic formation, or disputed derivation do not make the ancestry more definite than the forms actually named. In present English, the noun sense is "the fruit of the hawthorn; to hesitate in speech with a drawling sound", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as hawthorn and hem. Its semantic neighborhood includes hesitate, falter, and stammer, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Old English haga.
