decasyllabic

The form, though not finished with the perfection of the French decasyllabic, is by no means of a very uncouth description.

On one occasion, one of our children, a little boy, had been spending some time over a number of decasyllabic lines.

This is no less true of the decasyllabic verse, when compared with the full sonority of Lycidas, than of the shorter measures.

Nearly all of Chaucer's tales that are in stanzas are early, whilst all that are in decasyllabic couplets are late.
