The Myth of "They Understood Me

I keep seeing advice to simply "keep communicating" and let errors sort themselves out through exposure. That is dangerously misleading for a language as structurally different from Korean as English. Dropping an article or plural -s may go unnoticed in casual speech, but in writing it changes the meaning entirely — "the policy" is not the same as "a policy," and "information" is not "informations." Correcting these patterns once with a clear rule prevents them from becoming fossilized errors that confuse readers long after the conversation ends.
