Bill gets little money resulting in stress (6)
I believe the answer is:
accent
'stress' is the definition.
(accent can mean to emphasise or stress)
'bill gets little money' is the wordplay.
'bill' becomes 'ac' (short for account).
'gets' means one lot of letters go next to another.
'little money' becomes 'cent' (coin of little value).
'ac'+'cent'='ACCENT'
'resulting in' acts as a link.
(Other definitions for accent that I've seen before include "A diacritic mark" , "Special emphasis" , "feature of dialect?" , "Speech inflection" , "pitch" .)
