Shade of flowering tree in India, during visit to north (5)
I believe the answer is:
lilac
'shade of flowering tree in' is the definition.
'lilac' can be an answer for 'shade' (lilac is a shade of purple). I am not certain of the 'of flowering tree in' bit.
'india during visit to north' is the wordplay.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'during' is an insertion indicator.
'visit' becomes 'call' (synonyms).
'to north' shows that the letters should be reversed in order (in a down clue, letters go up or 'north').
'i' going inside 'call' is 'calil'.
'calil' reversed gives 'LILAC'.
Can you help me to learn more?
(Other definitions for lilac that I've seen before include "Fragrant shrub; colour" , "Lavender-coloured" , "Genus Syringa shrub" , "Drop by about one, turning" , "garden ornamental" .)
