Little fellow has desire after time (5)
I believe the answer is:
titch
'little fellow' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'desire after time' is the wordplay.
'desire' becomes 'itch' (itch is a kind of desire).
'after' means one lot of letters go next to another.
'time' becomes 't' (abbreviation).
'itch' put after 't' is 'TITCH'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for titch that I've seen before include "Small man (colloq.)" , "Little one" , "small one" , "Short person" , "One's very short" .)
