Key



Even native speakers of English sometimes have trouble with words because of a confusing feature: multiple meanings. If a word is old enough, it probably will have accumulated layers of meaning—sometimes astonishingly contradictory.

Richard from Empire, Michigan, pointed out that such a word is key. The meaning that comes to mind immediately is the notched metal device used to lock or unlock a door or other barrier. From there, it becomes a wild ride. Branching meanings include
  • spiritual authority (Matthew 16:19)
  • a symbol of office
  • a symbol of access, as in key to the city
  • a means to a desired objective
  • a position with strategic advantages
  • a bribe or inducement
  • a solution or explanation
  • a means of decrypting a code or cipher
  • the part of a textbook  that contains solutions
  • a list containing an explanation of symbols, abbreviations, etc.
  • in botany and zoology, descriptive features used in identification
  • an essential element
  • in chess, the first move in the solution of a problem
  • a central stone in an arch
  • a piece of wood or metal that locks parts together
  • a dry fruit
  • an instrument for turning tuning pegs of a stringed instrument
  • an instrument for winding a clock
  • a component that opens or closes a valve
  • the roughness of a surface that enables plaster to adhere to it
  • the free-throw lane and circle in basketball
  • a note or a tone
  • the tenor of a piece of writing
  • the prevailing tones in a painting
  • a lever on a musical instrument
  • a lever on a telegraph, computer, etc.
  • something of crucial importance

Then there’s the key that means a low-lying island or reef and the slang use of key that means a kilogram of an illegal drug,

Now I’m all keyed up.

Isn't the key that is the low lying island or reef spelled quay?

Think Key West, Key Largo, Florida Keys. The OED defines quay as "A man-made bank or landing stage, typically built of stone, lying alongside or projecting into water for loading and unloading ships."

Not to belabor this, but couldn't these New World "keys" be derived from the Old World "quay" instead of being an entirely new meaning for key?
PS Key for illegal drugs is shorthand for kilo, shorthand for kilogram.

The direct antecedent of key was cay, and if you track variations back to Anglo-French, it had a variety of spellings, including quai, which is obviously related to quay. So in a non-linear way, all three are actually the same form. Than ks for elucidaing, Librarian Judy.
