Expert writing Tips

Best practice

Always follow "realised" with "that" to introduce the content of your realization or use "realised" on its own when the context is clear. For example, "I realised that I was wrong", or "I realised my mistake".

Common error

Avoid using the preposition "of" after "realised". This is a common grammatical error. Always use "that" to introduce the clause explaining what you realised, or rephrase the sentence to use "realised" without any preposition.

Linguistic Context

The phrase "I realised of" functions as an incorrect attempt to express understanding or awareness. In standard English, the verb "realise" (or "realize" in American English) typically takes a "that" clause or a direct object, not a prepositional phrase with "of". The Ludwig AI confirms this grammatical error.

Ludwig's WRAP-UP

The phrase "I realised of" is identified by Ludwig as grammatically incorrect. The correct form is "I realised that" or simply "I realised" followed by an object. Although examples exist, primarily in news and media sources, this usage is considered a grammatical error. When writing or speaking, avoid using "of" after "realised". Alternatives such as "I understood" or "I became aware" may also be suitable depending on the intended meaning. Following these guidelines ensures clear and grammatically correct communication.

FAQs

How to properly use "I realised" in a sentence?

The correct way to use "I realised" is either followed by "that" and a clause (e.g., "I realised that I needed to study more") or with a direct object (e.g., "I realised my mistake"). Avoid using "I realised of".

Is it grammatically correct to say "I realised of"?

No, "I realised of" is not grammatically correct in standard English. The correct usage is "I realised that" or simply "I realised" followed by the object of your realization.

What can I say instead of "I realised of"?

What's the difference between "I realised that" and "I realised of"?

"I realised that" is the grammatically correct way to express a realization, introducing a clause that explains what was realised. "I realised of" is not standard English and should be avoided. Use "I realised that" to properly introduce the realized information.
