Note lass is like a queen! (5)
I believe the answer is:
regal
'like a queen' is the definition.
'note lass' is the wordplay.
'note' becomes 're'.
'lass' becomes 'gal' (I've seen this before).
're'+'gal'='REGAL'
'is' is the link.
(Other definitions for regal that I've seen before include "'Majestic, royal (5)'" , "Magnificent, dignified" , "Grand and imposing" , "Imperial, majestic" , "befitting a king" .)
