To turn up with this is pushy (3)
I believe the answer is:
shy
'to turn' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'up with this is pushy' is the wordplay.
'SHY' is hidden in amongst the letters.
However, I am uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for shy that I've seen before include "Timid (around people)" , "Embarrassed in company" , "Nervous with others" , "Coy" , "Reserved" .)
