Although some experts accept them and theirs with crazy words, most do not, and many teachers and employers consider the plural to be false. To be sure, you work for a correspondence between the singulated words and the pronouns that relate to them. Admittedly, the use of the singular in a formal context can still cause a few eyebrows raised, so be careful when submitting work to a particularly traditional teacher or teacher. But the page is turning, and English will soon be more effective because of such uses: the precursor of the singular can be a pronoun like someone, anyone or anyone, or an interrogative pronoun like who: the singular them. A singular precursor requires a singular reference pronoun. Since it is no longer accepted as a generic pronoun that relates to a person of both sexes, it has become common in the language and in informal writing to replace the plural pronouns of the third person she, she, she and herself and the non-standard singular. While this use is accepted in an occasional context, it is still considered non-grammatical in formal writings. Knowing that „they“ can be used to refer to individual people allows authors to prevent them from being used for regular use. It is also important for people whose gender is neither male nor female. In the words of the Chicago Manual (17 ) „Some people do not identify with a sexist pronoun, but with the pronoun they and its forms or another gender-neutral singular pronoun; Such a preference should be respected in general. The pronoun is often used as singular pronouns of the third person which is neuter between the masculine and the feminine. At a time limited to informal use. it is now increasingly accepted in formal usage, especially in [American English].
Introduction to your pronouns: If you`re not sure how best to ask for someone`s pronouns, you can imagine yourself and the pronouns you use. Thus, you invite the person to also give his pronouns if they wish. For example, the 7th edition of the APA Publication Manual contains guidelines on the use of singular publications for unprejudiced writing.  The answer is then the one you are likely to enter all the time. You don`t need to reconsider things and force yourself to say they`re happy. There`s no reason why the most intuitive solution — they`re happy — can`t be happy in the only column next to you`re happy. The Cambridge Grammar of the English Language discusses the pre-scripturist argument that it is a plural pronoun and that the use of them with a singular „precursor“ is therefore contrary to the rule of concordance between precursors and pronouns, but considers that, although they are primarily plural, they can be singular even in a derived sense, comparable to the supposedly extended meaning of that one to include the female sex.  In some sentences, typically those that contain words like all or all, the morphologically singular precursor does not refer to a single entity, but is „anaphorically related“ to the associated pronoun to display a number of pairwise relationships, as in the sentence: William Strunk Jr. . . .
