Asian vehicle concealed in Kensington Gardens (5)
I believe the answer is:
tonga
'asian vehicle' is the definition.
'tonga' can be an answer for 'vehicle' (I have seen 'Light vehicle' mean 'tonga' so perhaps 'vehicle' could also mean 'tonga'). I'm not certain of the 'asian' bit.
'concealed in kensington gardens' is the wordplay.
'concealed in' indicates the answer is hidden within the clue.
'TONGA' is hidden in the letters of 'kensington gardens'.
Can you help me to learn more?
(Other definitions for tonga that I've seen before include "Horse-drawn vehicle" , "Tropic island" , "Pacific island kingdom" , "transport" , "South Pacific island group country" .)
