Greet a person getting something to eat round the corner (6)
I believe the answer is:
salute
'greet a person' is the definition.
'salute' can be an answer for 'greet' (saluting is a kind of greeting). I'm not certain of the 'a person' bit.
'something to eat round the corner' is the wordplay.
'something' becomes 'alu' (I can't explain this - if you can you should believe this answer much more).
'to eat' means one lot of letters goes inside another (word on the right has word on the left to eat).
'round' indicates putting letters inside.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'corner' becomes 'SE' (south east corner of something).
't' put within 'se' is 'ste'.
'alu' going into 'ste' is 'SALUTE'.
'getting' is the link.
Can you help me to learn more?
(Other definitions for salute that I've seen before include "Acknowledge (superior)" , "Greet in military style" , "Hail, greet" , "Greet with a sign" , "Mark" .)
