Find leprechauns ungrateful, though they're somewhat overlooked (6)
I believe the answer is:
unsung
'somewhat overlooked' is the definition.
'unsung' can be an answer for 'overlooked' (I've seen this before). I am not sure about the 'somewhat' bit.
'find leprechauns ungrateful though' is the wordplay.
'find' indicates a hidden word (I've seen 'found' mean this).
'UNSUNG' is hidden within 'leprechauns ungrateful though'.
'they're' is the link.
Can you help me to learn more?
(Other definitions for unsung that I've seen before include "Not famous or acclaimed, hero perhaps" , "Without 1D [RECOGNITION]" , "Not honoured" , "Lacking due recognition" , "not recognised" .)
