Almost everyone I see gets a greeting (5)
I believe the answer is:
aloha
'greeting' is the definition.
(I've seen this before)
'almost everyone i see gets a' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'everyone' becomes 'all' (I've seen this before).
'i see' becomes 'oh' (both can mean 'I understand').
'gets' says to put letters next to each other.
'all' with its final letter taken away is 'al'.
'al'+'oh'+'a'='ALOHA'
(Other definitions for aloha that I've seen before include "16 across in Hawaii" , "Hawaiian hello or goodbye" , "A Polynesian hello or goodbye" , "Hawaiian farewell" , "Hello or goodbye in Hawaii" .)
