Dealing with a burden (6)
I believe the answer is:
across
'dealing with a burden' is the definition.
I can't judge whether this defines the answer.
'with a burden' is the wordplay.
'with' means one lot of letters go next to another.
'burden' becomes 'cross' (someone's particular burden is their cross).
'a' next to 'cross' is 'ACROSS'.
Can you help me to learn more?
(Other definitions for across that I've seen before include "To the opposite side" , "As this is entered" , "Clue with solution not going in the direction of this one!" , "Clues like this" , "this venue" .)
