Pressure a daily feature, maybe? Just a bit (8)
I believe the answer is:
particle
'just a bit' is the definition.
(a small bit)
'pressure a daily feature maybe?' is the wordplay.
'pressure' becomes 'p' (abbreviation).
'a daily feature maybe?' becomes 'article' (daily can mean a newspaper).
'p'+'article'='PARTICLE'
(Other definitions for particle that I've seen before include "Crumb" , "Small bit" , "Small unit of matter" , "Grain, tiny piece" , "Small amount" .)
