There are three accent patterns for two syllable words.

1.  Accent on the first syllable:

The accent is usually on the first syllable in two-syllable words.  This occurs in the words dollar, toothbrush, and airport.

2.  Accent on the second syllable:

When a word has a prefix in the first syllable then the root in the second syllable is usually accented on the second syllable.  This occurs in the words descend, exclude, and translate.

3.   Accent on either the first or second syllable:

If a word can function as both noun and verb they are accented differently.  The noun is accented on the prefix or the first syllable.  The verb is accented on the root-word or the second syllable.    This occurs in the words address, present, and record.
