Potency vs. Potential
'Potency' refers to active strength or power to cause an immediate effect, while 'potential' refers to unrealized capability that may develop in the future.
Gold Rule
Use in Specific Contexts

Word Origin
Derived from Latin 'potentia' (power, capability), from 'potens', the present participle of 'posse' (to be able).
Usage Notes
In contemporary English, 'potency' usually refers to active chemical/pharmacological strength or the persuasive power of arguments, rather than raw physical strength.
