耳の大きい

I heard this phrase a while ago and it's been bugging me since. Is this
correct? I have looked and heard different answers from both sides, but I'm
still quite unsure.

Although the
[question](https://japanese.stackexchange.com/questions/14056/noun-%E3%81%AE-
adjective) was asked on the site, I want to ask again since it's from 2014.
Maybe they were right?

This was a stand-alone phrase in a YouTube video.

question
grammar particle-の
Is "noun + の + adjective" correct/allowed?
Whether or not it is allowed/correct depends on the context. By itself, you
would be well advised to not use this construction in a regular conversation,
since it is wrong/odd.

There are examples however, where this phrase is correct. For example in old
Japanese, が and の were used interchangeably, so it can be correct in a
historic context.

Most commonly, this construction is used as an abbreviation if it's clear from
the context who or what the sentence is about (耳の大きい+[ _omitted noun_ ]). You
mentioned that you encountered this phrase in a YouTube video, so I think it's
likely that it refers to something mentioned in that video (I guess something
with ears?!).

A typical example would be, that the speaker made a statement about a
person/animal, then realized that he/she forgot to mention an important piece
of information (the big ears) and then immediatly adds this abbreviated
sentence to leave it up to the listener to figure out the correct meaning and
grammar.

answer
耳の大きい in isolation is not a valid sentence, but it is correct as a [relative
clause](https://japanese.stackexchange.com/a/14550/5010) with [ga-no
conversion](https://japanese.stackexchange.com/q/12825/5010) applied. For
example, the following sentences are correct.

> 耳 **の** 大きいゾウを見ました。  
>  = 耳 **が** 大きいゾウを見ました。
>
> I saw an elephant whose ears are big.

Here, 耳 **が** 大きい and 耳 **の** 大きい are modifying ゾウ as a relative clause, in
which case が and の are (usually) interchangeable.

For 耳の大きい to make sense, it **must** be followed by another noun. Otherwise,
it's just a strange sentence "fragment". For example, if 耳の大きい is the only
phrase printed on a T-shirt, it's plain wrong.
