I'm not sure if the phrase, our daily life, is correct. should it be 'our daily lives'?
I think it is difficult to distinguish the countable noun from uncountable noun especially when they are the same word.
For example, the word 'application' could be countable as well as uncountable, but I don't know when it should be the countable noun, and when it could not be rhe countable noun.
It there any way for me to distinguish these?
Welcome to the forum. I donít think there is any rule or set guidelines. If you are unsure of any particular noun, the only way is to use a good dictionary for correct identification. Standard dictionaries use the symbols [C] and [U] to identify countable and uncountable nouns.
