In particular, I time myself coming back (4)
I believe the answer is:
item
'in particular' is the definition.
'item' can be an answer for 'particular' (I've seen this in another clue). I'm not certain of the 'in' bit.
'i time myself coming back' is the wordplay.
'time' becomes 't' (abbreviation).
'myself' becomes 'me'.
'coming back' says the letters should be written in reverse.
'me' in reverse letter order is 'em'.
'i'+'t'+'em'='ITEM'
Can you help me to learn more?
(Other definitions for item that I've seen before include "A thing or unit" , "Entry (in an account)" , "Two people romantically linked" , "One unit on a list" , "See couple" .)
