4. The iamb ( ̆ ̄ ), the trochee ( ̄ ̆ ), and the anapæst ( ̆ ̆ ̄ ) are by far the commonest English feet; in fact, the great bulk of English poetry is composed of them.
The spondee.
5. The spondee ( ̄ ̄ ) is not so unusual as has sometimes been thought; but owing to the commonness of most syllables, especially in thesis, it may often be passed as an iamb, and sometimes as a trochee.
The dactyl.
6. The dactyl ( ̄ ̆ ̆ ), on the other hand, though observable enough in separate English words, does not seem to compound happily in English, its use being almost limited to that of a substitute for the trochee. Used in continuity, either singly or with other feet, it has a tendency, especially in lines of some length, to rearrange itself into anapæsts with anacrusis. In very short lines, however, this "tilt" has not always time to develop itself.
The pyrrhic.
7. The pyrrhic ( ̆ ̆ ) may occur in English, but is rarely wanted (see note above on spondee).
The tribrach.
8. The tribrach ( ̆ ̆ ̆ ), however, has become not unusual.
