1. It was a clear and sunny weather.
I wonder if the article is needed here.
A native speaker told me this expression is very common in Canada.

2. It went to a corn field and saw the corns were big and plentiful.
The word corn is not countable when it refers to the corn crop.
I want to know if the sentence above is ok.

Countable or uncountable nouns often sound very flexible.
Anyone coluld help explain? Thanks in advance.

Answer

1. It was a clear and sunny weather.
The weather was sunny and clear.

2. It went to a corn field and saw the corns were big and plentiful.
He/She/They/We/I went to a cornfield and saw the corn was tall and plentiful.

Countable nouns are pretty difficult for non-native speakers. Even native speakers don't always understand why they are written a certain way. It is one of those grammar lessons we pick up naturally over time. With enough practice, you will start to notice when certain countable nouns just don't "sound right" or "look right" to you.

I'm sure someone on here can give you a good definition of how to use countable nouns, but you might end up more confused haha.
