Ensure clarity by specifying the referent of "their" to avoid ambiguity. For example, instead of "The team celebrated in their way", specify "The team celebrated in their unique way".

Avoid using "in their" when referring to a singular subject. For example, instead of "Each student should bring "in their" own lunch," use "Each student should bring his or her own lunch" or, better yet, "All students should bring "in their" own lunches."
