in ancient poetry, a sort of verse, so called from its consisting either wholly, or in great part, of iambus's. See IAMBUS.

Ruddiman makes two kinds of iambic, viz. dimeter and trimeter; the former containing four feet, and the latter six. And as to the variety of their feet, they consist wholly of iambus's, as in the two following verses of Horace:

Dimeter. \[ \text{Dim. Iam.} \]

Trimeter. \[ \text{Trim. Suis} \]

Or, a dactylus, spondeus, anapaetus, and sometimes tribrachys, obtain in the odd places; and the tribrachys also in the even places, excepting the last.—Examples of all which may be seen in Horace; as,

Dimeter. \[ \text{Canida trahavit dapes} \]

Trimeter. \[ \text{Quo quid fecit, si ruat, lacu cur dexterae?} \]
