Is this worn on the head to displace the rain? (7)
I believe the answer is:
hairnet
'is this worn on the head' is the definition.
The definition suggests a singular noun which matches the answer.
'displace the rain?' is the wordplay.
'displace' is an anagram indicator (I've seen 'displaced' mean this).
'the'+'rain'='therain'
'therain' anagrammed gives 'HAIRNET'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for hairnet that I've seen before include "This protects beehive, for instance" , "keeper of locks" , "Headgear" , "A woman may wear this" , "In heart (anag)" .)
