Indian greeting a Pole in Tyneside (7)
I believe the answer is:
namaste
'indian greeting' is the definition.
'a pole in tyneside' is the wordplay.
'pole' becomes 'mast' (mast is a kind of pole).
'in' indicates putting letters inside.
'tyneside' becomes 'NE' (region in North East of England).
'a'+'mast'='amast'
'amast' inserted inside 'ne' is 'NAMASTE'.
(Other definitions for namaste that I've seen before include "greeting" , "sign of respect" , "salutation" .)
