Lazy fellow I had left with hesitation (5)
I believe the answer is:
idler
'lazy fellow' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'i had left with hesitation' is the wordplay.
'i had' becomes 'I'd' (common contraction).
'left' becomes 'L' (common abbreviation).
'with' says to put letters next to each other.
'hesitation' becomes 'er' (sound used when hesitating).
'id'+'l'+'er'='IDLER'
Can you help me to learn more?
(Other definitions for idler that I've seen before include "comparatively shoddy?" , "Dodger" , "Unpowered guide pulley" , "One reluctant to work" , "Layabout; ship crewman not on watch" .)
