like some pentameters (6)
I believe the answer is:
iambic
'like some pentameters' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for iambic that I've seen before include "a type of poem" , "Of a metrical foot of two syllables, one short and one long" , "description of some verse" , "Of verse, made up of metrical feet - may be pentameter" , "Line of poetry with unstressed-stressed syllables" .)
