Daughter to notice another relative (3)
I believe the answer is:
dad
'another relative' is the definition.
'dad' can be an answer for 'relative' (dad is a kind of relative). I am not sure about the 'another' bit.
'daughter to notice' is the wordplay.
'daughter' becomes 'd'.
'to notice' becomes 'ad'.
'd'+'ad'='DAD'
Can you help me to learn more?
(Other definitions for dad that I've seen before include "Father, in short" , "Mum's mate" , "Popular and informal father" , "Popular father - a palindrome" , "Relation" .)
