Day passed, I basically did nothing (5)
I believe the answer is:
idled
'did nothing' is the definition.
(I've seen this before)
'day passed i basically' is the wordplay.
I cannot really see how this works, but
'day' could be 'd' (abbreviation for day) and 'd' is located in the answer.
'passed' could be 'led' (leading is a kind of passing) and 'led' is found in the answer.
'i' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for idled that I've seen before include "Was lazy" , "Loafed, lazed about" , "Did little or nothing" , "Loitered" , "sat back" .)
