Expert writing Tips

Best practice

Pair the phrase with specific evidence in subsequent sentences to reinforce the certainty you have established.

Common error

Do not use other adverbs of certainty alongside 'undoubtedly', such as writing "she undoubtedly certainly knows". This creates a tautology that weakens the professional tone of your writing. Stick to one strong adverb to maintain clarity and impact.

Linguistic Context

The phrase "she undoubtedly knows" functions as a declarative statement within a sentence. It combines a subject pronoun ("she") with an intensive adverb ("undoubtedly") that modifies the finite verb ("knows"). This grammatical construction is used to remove any shadow of suspicion regarding the subject's knowledge. Ludwig AI confirms its status as a correct and highly effective way to emphasize certainty.
