Why should we avoid using 'a', 'an', or 'one' with uncountable nouns?

Uncountable nouns refer to things that cannot be counted individually, such as substances or concepts like "water," "information," or "happiness." Using articles like 'a', 'an', or 'one' suggests that the noun being referred to can be counted, implying that there are distinct, countable units of that noun. For instance, saying "a water" would incorrectly suggest that there are units of water that can be counted, which is not the case. This is why avoiding these articles with uncountable nouns is necessary for grammatical correctness and clarity. The presence of these articles may imply multiplicity when discussing items that are inherently singular or collective, leading to misunderstandings in communication.

The other options do not accurately address the grammatical reason related to countability and clarity. Some may suggest formality or confusion, but they do not pinpoint the core principle of how articles function in English grammar concerning count and non-count nouns.
