Shy and tiny man rejected girl (5)
I believe the answer is:
timid
'shy' is the definition.
(I know that shy can be written as timid)
'tiny man rejected girl' is the wordplay.
'tiny man' becomes 'tim' (short for Timothy. I am not sure about the 'tiny' bit.).
'rejected' says the letters should be written in reverse.
'girl' becomes 'Di'.
'di' reversed gives 'id'.
'tim'+'id'='TIMID'
'and' is the link.
Can you help me to learn more?
(Other definitions for timid that I've seen before include "Easily scared" , "not forward" , "Bashful or fearful" , "doormat" , "Easily frightened" .)
