Indolent type I had left, with hesitation (5)
I believe the answer is:
idler
'indolent type' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'i had left with hesitation' is the wordplay.
'i had' becomes 'id' (common contraction).
'left' becomes 'l' (common abbreviation).
'with hesitation' becomes 'er' (I've seen this in other clues).
'id'+'l'+'er'='IDLER'
Can you help me to learn more?
(Other definitions for idler that I've seen before include "One who doesn't want to work" , "Bum" , "Couch potato" , "Dodger" , "stationary car perhaps?" .)
