Formula in geometry maybe or English grasped by other people (7)
I believe the answer is:
theorem
'formula in geometry' is the definition.
'theorem' can be an answer for 'formula' (I've seen this before). I am not certain of the 'in geometry' bit.
'or english grasped by other people' is the wordplay.
'english' becomes 'E' (abbreviation).
'grasped by' means one lot of letters goes inside another (I've seen this in other clues).
'other people' becomes 'them' (those people over there).
'or'+'e'='ore'
'ore' placed inside 'them' is 'THEOREM'.
'maybe' acts as a link.
Can you help me to learn more?
(Other definitions for theorem that I've seen before include "Mathematical axiom" , "Proposition not self-evident but proved by a chain of reasoning" , "this has been established" , "Mathematical formula" , "Hero met (anag) - principle that's proven" .)
