Like some verse coming from this writer's biro? (6)
I believe the answer is:
iambic
'like some verse' is the definition.
(iamb is a type of poetic foot)
'this writer's biro?' is the wordplay.
'this writer's' becomes 'iam'.
'biro?' becomes 'bic' (both are pen manufacturers).
'iam'+'bic'='IAMBIC'
'coming from' is the link.
(Other definitions for iambic that I've seen before include "Shakespearean verse metre" , "Of a metrical foot of two syllables, one short and one long" , "Like some pentameters" , "Consisting of short-long metrical feet" , "description of some verse" .)
