Splendid fellows (5)
I believe the answer is:
regal
'splendid' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for regal that I've seen before include "Like a queen?" , "Royal - lager (anag)" , "King-like" , "Befitting a monarch" , "Grand and imposing" .)
