A tail, perhaps, caught right in what should catch the head (6)
I believe the answer is:
lariat
'what should catch the head' is the definition.
I can't tell whether this definition defines the answer.
'a tail perhaps caught right' is the wordplay.
'perhaps' indicates anagramming the letters.
'caught' is an insertion indicator.
'right' becomes 'ar' (I've seen this in other clues).
'tail' anagrammed gives 'liat'.
'liat' going around 'ar' is 'LARIAT'.
'in' is the link.
Can you help me to learn more?
(Other definitions for lariat that I've seen before include "Line of cowboy" , "Rope to lasso or tether" , "Mortar-spreading tool" , "Cowboy's rope (of Spanish origin)" , "A trail (anag) - rope" .)
