Spotting Errors— Concepts, Formulas & Shortcuts
- Subject–verb agreement: find the true subject, ignoring phrases like "of the students" in between.
- "One of the …" is always followed by a plural noun and a singular verb.
- Comparatives from Latin — senior, junior, superior, inferior, prior — take "to", never "than".
- "Since" is used with a point in time; "for" with a duration.
- Each, every, either, neither, none of the two → singular verb.
- Present perfect ("have been") cannot combine with a finished past time expression.
