Female writer getting wet (6)
I believe the answer is:
dampen
'wet' is the definition.
(dampening is a kind of wetting)
'female writer getting' is the wordplay.
'female' becomes 'dam' (dam is a kind of female**).
'writer' becomes 'pen' (I've seen this before).
'getting' means one lot of letters go next to another.
'dam'+'pen'='DAMPEN'
(Other definitions for dampen that I've seen before include "Make slightly moist, or discourage" , "Stifle" , "Make moist or depressed" , "Discourage in moist manner" , "Make moist or depress spirits" .)
