Word List and Usage: F
faculty, faculties Lowercase. Faculty is a mass (collective) noun—one that denotes something uncountable because it refers to an indeterminate aggregation of people. As the subject of a sentence, a mass noun usually takes a singular verb. But in a collective sense, it may take either a singular or a plural verb form. A singular verb emphasizes the group: The faculty is invited to a reception on March 16. A plural verb emphasizes the individual members: Faculty were to arrive at the ceremony by noon. (A better way of wording that sentence is: Faculty members were to arrive at the ceremony by noon.) The plural noun is faculties: The faculties of New York University and Columbia University held a joint conference in May.

farther, further Farther refers to physical distance: She ran farther than he did. Further refers to an extension of time or degree: Further research is needed to prove his hypothesis.
