The word milton is a trochee.

A trochee is a metric foot with a stressed syllable followed by an unstressed syllable. Milton is pronounced MILton. If Milton was an iamb, it would not vary from the traditional iambic pattern. Milton cannot be a dactyl because a dactyl is three syllables. The first syllable is stressed and is followed by two stressed syllables.
