Finally time to support burdened fellow (2,4)
I believe the answer is:
at last
'finally' is the definition.
(synonyms)
'time to support burdened fellow' is the wordplay.
'time' becomes 't' (abbreviation).
'to support' is a charade indicator (letters next to each other) (in a down clue, some letters hold others up).
'burdened fellow' becomes 'atlas' (I can't explain this - if you can you should believe this answer much more).
't' after 'atlas' is 'AT LAST'.
Can you help me to learn more?
(Other definitions for at last that I've seen before include "Finally, ultimately" , "'In the end (2,4)'" , "Finally, after a long wait" , "Finally, after much delay" , "None too soon" .)
