Expert writing Tips

Best practice

Always use the correct verb form "I substitute" instead of the grammatically incorrect "I substitutes". Remember that the first-person singular pronoun "I" requires the base form of the verb in the simple present tense.

Common error

Avoid conjugating the verb incorrectly after the pronoun "I". The correct form in the present tense is "I substitute", not "I substitutes". Using "I substitutes" introduces a grammatical error that detracts from the clarity and correctness of your writing.
