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 judge whether this definition defines the answer.
'a tail perhaps caught right' is the wordplay.
'perhaps' is an anagram indicator.
'caught' means one lot of letters goes inside another.
'right' becomes 'r' (common abbreviation).
'a'+'tail'='atail'
'atail' is an anagram of 'laiat'.
'laiat' going around 'r' is 'LARIAT'.
'in' acts as a 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" .)
