Expert writing Tips
Best practice
When aiming for clarity, always follow "assumed" with "that" or rephrase your sentence to avoid the grammatical error. For example, instead of "I assumed to know", use "I assumed that I knew."
Common error
Avoid using "assumed to" as a direct substitute for "assumed that". This construction is grammatically incorrect and can confuse readers. Instead, ensure you use "assumed that" to introduce a subordinate clause, or consider alternative phrasing.
