Be good enough to hold strange, tailless bird (4)
I believe the answer is:
dodo
'bird' is the definition.
(dodo is a kind of bird)
'be good enough to hold strange tailless' is the wordplay.
'be good enough to' becomes 'do' (I am not sure about this - if you are sure you should believe this answer much more).
'hold' indicates putting letters inside.
'strange' becomes 'odd' (I've seen this before).
'tailless' means to remove the last letter.
'odd' with its last letter taken off is 'od'.
'do' going around 'od' is 'DODO'.
Can you help me to learn more?
(Other definitions for dodo that I've seen before include "Bird (whose style of very out of fashion)" , "Idiot" , "Mauritian bird no more" , "Old bird" , "Two rooks - one was unable to fly" .)
