A wet type with much foolish pride (4)
I believe the answer is:
drip
'a wet' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for drip that I've seen before include "Trickle -- weakling" , "Hospital device; weak person" , "Flow in small drops" , "Sissy" , "Fall as from leaky tap" .)
