Need supporting from a suitable angle (4)
I believe the answer is:
lean
'need' is the definition.
The definition and answer can be both to do with fundamental existence as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'supporting from a suitable angle' is the wordplay.
'supporting' indicates the answer is hidden within the clue.
'LEAN' can be found hidden inside 'from suitable angle'.
Can you help me to learn more?
(Other definitions for lean that I've seen before include "Thin; heel" , "Incline to prop against" , "Of meat, with little or no fat" , "Slim; veer" , "Incline; (of person) thin" .)
