After all, it is the English teacher who receives the daily questions about usage from students, other faculty members, and the general public. I suggest that a large portion of our difficulties in handling usage questions comes not from unduly restrictive rules or the lack of reliable references, but from our failure to man our posts properly.” V. Louise Higgins, “Approaching Usage in the Classroom” (1960), in Readings in Applied English Linguistics 330, 331 (Harold Byron Allen ed., 2d ed. 1964).
