Clash with money-killer? (8)
I believe the answer is:
coincide
'clash' is the definition.
The definition and answer can be both to do with fundamental existence as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'with money-killer?' is the wordplay.
'with' is a charade indicator (letters next to each other).
'money' becomes 'coin' (coin is a type of money).
'killer?' becomes 'cide' (I can't explain this - if you can you should believe this answer much more).
'coin'+'cide' is 'COINCIDE'.
Can you help me to learn more?
(Other definitions for coincide that I've seen before include "agree" , "Occur at same time, place" , "Occur together" , "Happen together" , "Happen at the same time in unplanned way" .)
