THE IDEA, SIMPLY

The rule, with an example

Check one layer at a time: subject–verb agreement, verb form, countability, and sentence structure. A useful correction explains the problem rather than only replacing the words.

SEE IT IN CONTEXTShe have two assignments → She has two assignments. The singular subject she needs has.
Skills to work on in this practice
  • Find the part that needs changing
  • Explain the grammar behind the correction
  • Rewrite a sentence with the meaning intact

Use a three-step editing check

UseExampleWhy it works
Find the subjectThe list of tasks is on the desk.List, not tasks, controls the singular verb.
Check the timeWe finished yesterday.Yesterday gives a finished past time.
Check the nounI need some advice.Advice is uncountable; use a piece of advice to count one item.

Common mistake

Check: The list of tasks are long

Use: The list of tasks is long

Identify the head noun before choosing agreement.

How should I practise this?

Read the example and explain the choice before answering. After the exercise, write a new sentence using the same pattern. Revisit any answer you could not explain, even if you guessed correctly.
