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.

The phrase "I substitutes" is grammatically incorrect; the correct form is "I substitute".

While the intention is to communicate the action of replacing something, the incorrect grammar undermines clarity.
