Key difference

There is no pronunciation difference at all — night/knight are both /naɪt/, not/knot are both /nɒt/, new/knew are both /nuː/, and nit/knit are both /nɪt/. The only way to tell them apart is spelling and context — your ear alone can’t do it.

Why is the K even there?

Centuries ago, English really did pronounce that k— “knight” sounded closer to “k-nicht,” with both the k and a throaty sound at the end. Over time, English speakers stopped pronouncing the k before n, but the spelling never caught up. That’s why this exact pattern — a silent k before an n at the start of a word — shows up again and again: knee, knife, knob, knock, know, knuckle.

Example sentences

night:“We watched the stars all night.”

knight:“The knight protected the castle.”

not:“That is not what I meant.”

knot:“The rope was tied in a tight knot.”

new:“I just got a new pair of shoes.”

knew:“I knew you’d come.”

nit:“The school nurse checked everyone for nits.”

knit:“My grandmother taught me how to knit.”

The pattern isn’t perfect

Not every silent-k pair stays a true homophone. Know is literally “k” + “now” in spelling, but the vowel changed over time — now is /naʊ/ (like cow) while know is /noʊ/ (like go) — they don’t rhyme. And knead (to work dough with your hands) sounds exactly like need, but isn’t spelled by simply adding a k — the vowel letters differ too (knead vs. need). Don’t assume every kn- word matches its n- twin perfectly; check each one.
