iambic

the word 'iambic' has its origins in the greek 'iambos', which referred to a specific metrical foot and also to a genre of satirical poetry. the term likely entered english via latin 'iambus', preserving its core prosodic meaning. the suffix '-ic', of greek origin via latin, is a common adjectival ending used to form words meaning 'pertaining to'. thus, 'iambic' literally means 'pertaining to the iamb', a poetic unit defined by its unstressed-stressed rhythm, which became a fundamental building block of much english verse, most famously in the iambic pentameter of shakespeare.

Structure: iamb (a metrical foot) + ic (adjective-forming suffix) iamb (from latin iambus, from greek iambos, a metrical foot or a type of poem); ic (from latin -icus, from greek -ikos, suffix forming adjectives meaning 'of, pertaining to, or in the manner of').
