In the past, when we wrote about an unidentified individual, we would say: “Each employee who wants to enroll his/her family in benefits can check this box.”
Some people didn’t like his/her. They wanted her/his or his or her…or they fussed with tedious editing to avoid the situation. But now, “they” CAN BE SINGULAR! For example: “Each employee who wants to enroll their family…”
This usage is considered:
· Acceptable grammar. According to Merriam-Webster (definition 3), we can use “they” as the pronoun for an individual. Define_they
· Inclusive language. In fact, many nonbinary individuals prefer the use of they, them, their.
