How do you replace he and she in a sentence?
Increasingly, companies are removing "he" and "she" from their employee handbooks and replacing them with gender-neutral pronouns, such as "they," Merriam-Webster's word of 2019. The companies are doing this to make nonbinary individuals who do not identify as male or female feel included.
English grammar states that people are referred to as 'he' or 'she' and that all other objects are referred to as 'it' in the singular or 'they' in the plural. In many languages, such as French, German, Spanish, etc. objects have gender. In other words, things are referred to as 'he' or 'she'
