Some homographs are nouns or adjectives when the accent is on the first syllable, and verbs when it is on the second.
When the prefix "re-" is added to a monosyllabic word, the word gains currency both as a noun and as a verb.
Most of the pairs listed below are closely related: for example, "absent" as a noun meaning "missing", and as a verb meaning "to make oneself missing".
There are also many cases in which homographs are of an entirely separate origin, or whose meanings have diverged to the point that present-day speakers have little historical understanding: for example, "bat".
Also, some words only exhibit stress alternation in certain dialects of English.
