One Sound, Two Words

A minimal pair is two words that differ by just one sound: ship/sheep, bat/bet, light/right. They matter because mispronouncing a single sound sends an entirely different word.

Every language background has its own danger pairs. Spanish speakers confuse ship/sheep. Japanese speakers mix right/light. Arabic speakers swap b/p. At first, your brain may not hear the difference clearly because your native language trained it to treat those sounds as similar or identical.
