Those huge pants Romeo wears not hiding much (3-7)
I believe the answer is:
see-through
'not hiding much' is the definition.
I can't tell whether this definition defines the answer.
'those huge pants romeo wears' is the wordplay.
'pants' indicates anagramming the letters (UK informal term for 'nonsense' or 'rubbish').
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'wears' is an insertion indicator.
'those'+'huge'='thosehuge'
'thosehuge' is an anagram of 'seethough'.
'seethough' enclosing 'r' is 'SEE-THROUGH'.
Can you help me to learn more?
(Other definitions for see-through that I've seen before include "Transparent" , "Translucent" .)
