A burden describing some clues (6)
I believe the answer is:
across
'a burden describing some clues' is the definition.
I can't judge whether this defines the answer.
'a burden' is the wordplay.
'burden' becomes 'cross' (someone's particular burden is their cross).
'a'+'cross'='ACROSS'
Can you help me to learn more?
(Other definitions for across that I've seen before include "Traversing" , "From side to side, like this clue" , "sort of clue?" , "First word in any crossword" , "written like this?" .)
