unrecognizable

An unrecognizable person or thing is someone or something that you can't identify or tell apart from others.

When we talk about something being unrecognizable, it usually means that it's so different or altered from its original state that we can't recognize it anymore. Imagine you see a friend after they've been traveling abroad for months - their hair might be longer and their skin tone darker, making them look very different from when you last saw them. That's an example of someone being unrecognizable. Or think about a familiar park in your city that's undergone some major renovations - it might not look like the same place anymore, which makes it hard to recognize. This word can also be used for things like food or objects that have been so transformed by cooking or changes in their appearance that you wouldn't know what they started out as.
