Confused a year with shorter period (3)
I believe the answer is:
day
'shorter period' is the definition.
'day' can be an answer for 'period' (day is a kind of period). I'm unsure of the 'shorter' bit.
'confused a year with' is the wordplay.
'with' indicates a hidden word.
'DAY' is hidden in the letters of 'confused a year'.
Can you help me to learn more?
(Other definitions for day that I've seen before include "24 23 acrosses" , "Dawn to dusk" , "Particular date" , "Doris -, US actress" , "24-hour period" .)
