India has wise man with lines offering pictorial language (7)
I believe the answer is:
imagery
'pictorial language' is the definition.
'imagery' can be an answer for 'language' (I have seen 'Figurative language ' mean 'imagery' so perhaps 'language' could also mean 'imagery'). I'm unsure of the 'pictorial' bit.
'india has wise man with lines' is the wordplay.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'has' is a charade indicator (letters next to each other).
'wise man' becomes 'mage' (I've seen this before).
'with' says to put letters next to each other.
'lines' becomes 'ry' (abbreviation for railway).
'i'+'mage'+'ry'='IMAGERY'
'offering' acts as a link.
Can you help me to learn more?
(Other definitions for imagery that I've seen before include "Mental pictures - I am grey (anag)" , "Mental visions" , "Use of language to produce pictures in the mind" , "Descriptive language" , "paintings" .)
