Can I add -y to all nouns in conversation?
I heard many people add -y to nouns when they speak. Can I do that with all nouns?

It tastes lemon-y.
It feels christmas-y.
It looks mango-y.

Oh. Just noticed my examples are using with senses verbs. (Taste, look, feel).

In written, you would use the following instead?

- It tastes like lemon.
- it feels like Christmas.
- It looks like mango.
Thank you.

Answer

You can not add a “y” to most nouns, in speech or writing.
Some words, such as salty and lemony, can be used in both speech and writing.

I think you can more generally convert nouns to adjectives by adding “-like”, but you can’t do that with all nouns either.

Examples
This wine is too fruity.
I’m not eating them. They look too much like pomegranates.
Are wallabies kangaroo-like?
Did you buy a Honda Civic? It’s Civic-like, but it’s actually a Subaru.

Answer

Yes, you can, but I'd note that it's more of a thing for informal speech. The latter sentences are proper for writing and more formal speech.

Answer

Yes.
