Stimulate others to action and drop out (4)
I believe the answer is:
prod
'stimulate' is the definition.
(I've seen this in another clue)
'others to action and drop out' is the wordplay.
'drop' anagrams to 'PROD'.
Though, I am not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for prod that I've seen before include "Poke or spur" , "Poke with stiff finger to urge" , "Spur or goad" , "Induce action (with stick etc?)" , "Urge or stimulate" .)
