The Origin of Knight and Night
Understanding the origin makes the difference easier to remember.
Origin of Night
The word night comes from Old English “niht.” It has always referred to the dark part of the day. Over time, the spelling changed slightly, but the meaning stayed the same.
The silent “gh” comes from older pronunciation. Long ago, people pronounced it with a throat sound. Today, the “gh” is silent.
Origin of Knight
The word knight comes from Old English “cniht,” which meant “boy” or “servant.” Later, it became a title for mounted soldiers in medieval Europe.
In Middle English, the spelling changed to knight. The “k” used to be pronounced. Today, the “k” is silent.
That is why both words sound the same now. English kept old spellings even when pronunciation changed.
