Meanings of decasyllabic in English

This poem is written in decasyllabic assonanced verse, each stanza being terminated by a short line.

The decasyllabic couplet, so resonant in Dryden, so admirably turned and polished by Pope, was its favorite measure.

The usual forms of the couplet used continuously are the 4-stress or short couplet ("octosyllabic") and the 5-stress or heroic couplet ("decasyllabic").
