English distinguishes vowel pairs that plenty of other languages treat as a single sound — the short “i” in “ship” versus the long “ee” in “sheep” is the classic example, but there are several others that quietly cause confusion: “full” versus “fool,” “cart” versus “cut.” Many first languages have a smaller vowel inventory than English, which means some of these pairs may genuinely sound identical to your own ear until they’re pointed out.
Try this now. Say “ship” and “sheep” out loud, back to back, several times, deliberately exaggerating the length and mouth shape difference between them: shorter and more relaxed for “ship,” longer and wider for “sheep.” Record it and, if possible, ask a native English speaker whether the two versions sound clearly different to them — your own ear is the least reliable judge here, precisely because the distinction may not exist in your first language.
If a specific vowel pair keeps causing confusion in real conversations, it’s worth building a short personal list of minimal pairs — words that differ by exactly that one sound — and drilling them the same way, a few minutes at a time.
