- •"High" means elevated or is used as a noun (a record high).
Trick to remember it
- •"Hi" is just two letters, short like a quick greeting.
- •"High" has silent GH like "night", "light", "sight", longer, more elevated.
Quick rule
- •Is it the greeting? "Hi".
- •Is it the elevation, level, or maximum? "High".
Did you know?
The greeting "hi" appeared in American English in the late 19th century, possibly from "hey" or as a contraction of "hiya" (how are you). "High" comes from Old English "heah", the same root as German "hoch" and Dutch "hoog." The GH in "high" originally represented a fricative sound /x/ (like Spanish J or Scottish "loch") that English speakers stopped pronouncing in the 15th century but kept in spelling, giving us dozens of words with silent GH: night, light, right, tight, bright, fight, sight, might.
