FAQs
How can I rephrase "I keep doing" to sound more formal?
In formal contexts, consider alternatives such as "I continue to do", "I persist in doing", or "I repeatedly do". These options often convey a more professional tone than "I keep doing".
Is it correct to say "I keep to do" instead of "I keep doing"?
No, the correct form is "I keep doing". The verb "keep" in this context requires a gerund (verb ending in -ing), not an infinitive. Therefore, "I keep "to do"" is grammatically incorrect.
What's the difference between "I keep doing" and "I continue doing"?
"I keep doing" implies a sense of habit or persistence, while "I continue doing" simply indicates the action is ongoing. The nuance is subtle, but "I keep doing" often suggests the action is repeated over a longer period.
When should I use "I kept doing" instead of "I keep doing"?
Use "I kept doing" when referring to a past action that was repeated or continued over a period of time. "I keep doing" refers to a present or ongoing action. For example, "I kept doing it even though it was difficult" refers to the past, while "I keep doing it because I enjoy it" refers to the present.
