Expert writing Tips
Best practice
In formal academic or legal writing, prefer the uncontracted version "it is virtually certain" to maintain a professional tone.
Common error
Avoid using the adverb form of the adjective in this structure, such as 'it's virtually certainly'. The linking verb 'is' requires a subject complement (adjective), not an adverb. Always use 'certain' as the adjective being modified by the adverb 'virtually'.
