Confused Adjectives: Why They Feel Easy but Cause Big Mistakes

If you are learning English, confused adjectives can quietly hurt your confidence. You might know the words, but when you use them, people react strangely or misunderstand you.

I see this every day as a teacher.

A student says, “I am boring” instead of “I am bored.” Another student says, “cheap hotel” when they really mean “inexpensive hotel.”

The problem isn’t your intelligence. The issue is that many English adjectives look alike but feel different to native speakers.
