Tries hard for specialists dismissing pressure (6)
I believe the answer is:
exerts
'tries hard' is the definition.
I can't judge whether this defines the answer.
'specialists dismissing pressure' is the wordplay.
'specialists' becomes 'experts' (I've seen this before).
'dismissing' is a deletion indicator.
'pressure' becomes 'p' (abbreviation).
'experts' with 'p' taken out is 'EXERTS'.
'for' is the link.
Can you help me to learn more?
(Other definitions for exerts that I've seen before include "Makes use of" , "Brings into use, say strength" , "Brings into use or to bear" , "Forcefully applies (pressure)" , "Makes strenuous effort" .)
