Minor second role is welcome in Frozen? (5)
I believe the answer is:
child
'minor' is the definition.
(I know that minor can be written as child)
'second role is welcome in frozen?' is the wordplay.
I cannot quite see how this works, but
'second' could be 'd' and 'd' is located in the answer.
'welcome' could be 'hi' (both are greetings) and 'hi' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for child that I've seen before include "Young human" , "Kid" , "Nipper" , "Minor" , "Immature, irresponsible person" .)
