sexism

Sexist biases are encoded in our language. To help perpetuate a vocabulary that is fair to all genders, use ungendered language whenever you can.

Examples:

firefighter, not fireman
US representative, not Congressman
chair, not chairman
businessperson, not businessman

When possible, avoid he and his as inclusive references. Don't use or and slash-forms: he or she; she/he; his/her.

It is better to alter the sentence using third-person plurals instead of singular. For example: “All students plan their own programs.”

transgender person; transgender (or trans) woman

NOT The show was canceled since no one showed up.

subjunctive mood

Use the subjunctive mood of a verb for contrary-to-fact conditions and for expressions of doubts, wishes, or regrets:

If I were rich, I wouldn't have to work.
I wish it were possible to take back my words.

Sentences that express a contingency or hypothesis may use either the subjunctive or the indicative mood, depending on the context. In general, use the subjunctive if there is little likelihood that the contingency might come true:

If I were to inherit millions, I wouldn't have to worry about money.
BUT If this bill passes as expected, it will provide a tax cut.

syllabus/syllabi

Webster's lists syllabi first as the plural form.
