Language is a tool for expressing oneself, communicating, receiving, and understanding others.
Besides languages, we can use non-verbal language, such as actions, eye contact and facial expressions.

We communicate and receive feelings daily through nonverbal expressions. Nonverbal expressions are more likely to convey the true feelings of the person expressing them and are influenced by the recipient's unconscious bias.

I believe there are as many ways of expression and reception as there are people. It depends on the environment and culture in which you have been brought up, the number of vocabulary you have, the situation at that time, and your perception of things,
circumstances, perceptions, beliefs, etc.
There are so many possible settings.

For example,
English is a common language worldwide, but that doesn't mean we should speak correct English.
It is enough if the other person can understand what you say.
Language allows us to use it in various ways, so it is deeper and wider than we think.

I want to talk about the words "disabled person."
I used to think this term was inappropriate because it was too direct and might convey the meaning of discrimination.

However, what I learned at the College and my current exposure to various people's messages have greatly changed my perception.

There are two expressions in English that I learned at the College,
"Person-first language" and "Identity-first language."

"Person-first language" reinforces that people with disabilities are human and helps ensure that people with disabilities should be treated the same way as others without disability.
We say like a person who is blind, a student with a wheelchair, or a person with a disability.

In conversation and writing, respecting people as persons and avoiding stigmatizing situations is essential.
Person-first language seems to be recommended, especially when describing small children.

On the other hand, a certain number of voices oppose the "person-first language. This is the case with post-adolescent children, adult parties, or according to the views of the particular community itself. This surprised me.

These voices see themselves and their disability as part of their personality and culture and use language that brings that disability first with pride and dignity.
That is the Identity-first language.
We say like a disabled person, autistic person or Deaf community.

Regarding this, it is not a matter of which is correct.
What should we do if we are not sure?

"Ask the person concerned what they would prefer to be called."

This is probably the most appropriate.
As I said before, there are as many ways to receive a message as there are people. Even the same person may receive the message differently depending on the situation.

For example, I am Japanese, and I live in Canada.
When I am playing tennis with my Canadian friend,
I may feel slightly uncomfortable if someone says, "She is a Japanese person." because nationality has nothing to do with enjoying tennis.
Activities like sports, music, games, work, and study allow us to connect with others and enjoy them regardless of nationality and culture.

However, outside of work, in everyday life, in cultural interactions, and when expressing myself, I can be more convincing by saying "Japanese person" because I am proud to say that I was born and raised in Japan, and that is what makes me who I am today.

By the way,
My son is both a Canadian born and raised in Canada and a Japanese citizen.
According to Japanese law, he must choose one or the other in the future. There are still a few years to go, but I hope to hear his thoughts on his identity at some point.

Languages are tools.
If I refer to non-verbal language as a spirit,
what kind of spirit is put into language?
I want to keep this in mind when I use languages.

And what kind of spirit accompanies language? What action accompanies language?
I want to keep this in mind when I understand others.
