Frequently Asked Questions

Is “realise” spelled with an s or a z?

Both spellings are correct, but they belong to different regions. “Realise” is the British English spelling, while “realize” is the American English spelling, and both words mean exactly the same thing. Pick one spelling and use it consistently in a single piece of writing, so your reader never has to guess which style you follow.

What is the most formal way to say “realise”?

“Comprehend” is the strongest formal choice, because it suggests a full and careful understanding, not just a passing thought. “Perceive” and “discern” are also formal, while “acknowledge” works best when you accept a fact in writing, for example after careful consideration in a report or an apology. A Merriam-Webster definition of realize covers the same core meaning, so check it if you want the dictionary wording before you choose. For a formal phrase built on the same idea, see our guide to other ways to say “after careful consideration”.

Can I use “discover” instead of “realise”?

Yes, when the realisation feels like finding something out for the first time. “Discover” suits new facts, hidden details, and surprises, while “realise” suits a truth that was already in front of you. For instance, you discover a hidden fee on a bill, but you realise you forgot to pay it. If you want more example phrases, see our guide to other ways to say “for instance”.
