Manly enough to master some gauchos (5)
I believe the answer is:
macho
'manly' is the definition.
(I've seen this before)
'enough to master some gauchos' is the wordplay.
I cannot really see how this works, but
'master' could be 'ma' and 'ma' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for macho that I've seen before include "Ramboesque" , "Affectedly virile" , "Spiny lobster" , "Markedly manly?" , "Aggressively masculine" .)
