Though lazy, I'd almost gone ahead (4)
I believe the answer is:
idle
'though lazy' is the definition.
'idle' can be an answer for 'lazy' (similar in meaning). I'm unsure of the 'though' bit.
'i'd almost gone ahead' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'gone' becomes 'led' ('lead' can be a synonym of 'go').
'ahead' means one lot of letters go next to another.
'led' with its last letter taken off is 'le'.
'id'+'le'='IDLE'
Can you help me to learn more?
(Other definitions for idle that I've seen before include "Without work" , "Eric, perhaps" , "lndolent" , "goalless" , "Lazy - vain" .)
