Mannish vs Mennish

The two words 'Mannish' and 'Mennish' sound similar, and are often (wrongly) used interchangeably.

Mannish is the language spoken by all men, since the coming of Atama the Great. It is only the language, nothing else.

Mennish is the entire culture of men. For instance, Mennish Reckoning.
