Here's how it works:
* "His" refers to a male individual.
* It shows that something belongs to that male individual.
For example, in the sentence "He lost his keys," "his" indicates that the keys belong to the male individual referred to by "he."
To understand the literal meaning of "his," you need to consider the context in which it's used. The phrase itself doesn't have a meaning in isolation, but rather functions to indicate ownership within a larger sentence or phrase.
