A single woman touring India, a foolish person (5)
I believe the answer is:
idiot
'a foolish person' is the definition.
(I've seen this before)
'a single woman touring india' is the wordplay.
'a single' becomes 'I' (one).
'woman' becomes 'dot' ().
'touring' means one lot of letters goes inside another (touring can mean going round).
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'dot' placed around 'i' is 'diot'.
'i'+'diot'='IDIOT'
(Other definitions for idiot that I've seen before include "Stupid person" , "Charlie" , "Oaf" , "Mug" , "The - (Dostoievsky)" .)
