He thinks he can tell you what's going to take place (7)
I believe the answer is:
tipster
'he thinks he can tell you what's going' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'take place' is the wordplay.
I cannot quite see how this works, but
'take' could be 'r' (abbreviation for 'recipe', Latin for 'take') and 'r' is present in the answer.
'place' could be 'tip' (tip is a kind of place) and 'tip' is present in the answer.
The remaining letters 'ste' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for tipster that I've seen before include "Gambling advisor" , "Betting pundit" , "One advising betters" , "One predicting winners" , "One who sells betting advice" .)
