Language is the most basic medium of communication with each other. The communication using dialog cannot be beaten by any other source or medium of communication. This is why many people feel comfortable in communicating with their fellow countrymen or people who know their native languages.
Gendered language consists of words that are bias towards sex or gender. If you call someone a policeman or a policewoman, it indicates the gender specificity. In such a case, you can be gender-neutral by saying a police officer which conveys the message in the most gender-neutral way.
Some use pronouns like he/she or him/her to identify their gender. However, non-binary people may use pronouns such as they/them to keep themselves gender-neutral. This makes sense because non-binary people do not like to identify themselves as a specific gender and since we cannot make up a new word for them, they stick to the gender-neutral words like they/them.
There are a lot of words, job titles and greetings that are tied to a specific gender. The previous example of police officer shows that but if you dig deeper then you will find more gender-specific words. So let's take a look at the following infographic which shows a few gender-specific words and their gender-neutral alternatives.
