genderless pronouns - Each person have or has? And about "it"?

Each person have or each person has?

And more: Each person have/has its own way to learn or each person have/has his own way to learn?

I'm asking this because I found some contradictions on the internet and I'm here to get a more concise answer.

Thanks in advance!

Answer

You can use any of these alternatives,

Each person has his own way ...
Each person has his or her own way ...
Each person has her¹ own way ...
Each person has their own way ...

When I was young, Each person has his ... was common. Then, the preferred usage changed to Each person has his or her ... and later Each person has her¹ ....

Nowadays, singular they is also acceptable.

¹Also note that even though you can use her as a pronoun for someone who you don't know his or her gender, it's better to use his or her or singular their in general, unless they are all female.
