Oscar's confused about the way this clue goes (6)
I believe the answer is:
across
'clue goes' is the definition.
The answer and definition are not the same part of speech.
'oscar's confused about the way' is the wordplay.
'confused' indicates anagramming the letters.
'about' indicates putting letters inside.
'the way' becomes 's' (Compass direction - South).
'oscar' with letters rearranged gives 'acros'.
'acros' going around 's' is 'ACROSS'.
'this' is the link.
Can you help me to learn more?
(Other definitions for across that I've seen before include "From side to side, like this clue" , "Horizontally" , "Transverse" , "stride - athwart" , "14 of these clues are" .)
