What may be worn on the head to displace the rain? (7)
I believe the answer is:
hairnet
'what may be worn on the head' is the definition.
I can't tell whether this defines the answer.
'displace the rain?' is the wordplay.
'displace' indicates anagramming the letters (I've seen 'displaced' mean this).
'the'+'rain'='therain'
'therain' is an anagram of 'HAIRNET'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for hairnet that I've seen before include "It may keep locks" , "keeper of locks" , "Cover for head" , "It protects locks" , "cause of static shock?" .)
