heyda
heyda
English
“The word for the peak of something's power began as an exclamation of joy—a shout, not a noun.”
In the 1580s, heyda or heyday was an interjection—an exclamation of high spirits, something you shouted when you were excited. Shakespeare used it this way in Hamlet (1600): 'In the heyday of the blood.' It had no connection to time or peak or golden age. It was just a noise of pleasure, possibly from Low German heidā, an exclamation of surprise.
The transformation from exclamation to noun happened slowly. 'The heyday of the blood' meant the excitement of youth—blood running hot, spirits running high. Over the 1600s, heyday shifted from describing a feeling to describing the period in which that feeling occurs. The shout became a season.
By the 1700s, heyday meant the period of greatest vigor or success. Samuel Johnson defined it in his 1755 Dictionary as 'frolic; wildness.' But the meaning was already settling into something more dignified: not wild joy, but the peak of power, influence, or prosperity.
Modern English uses heyday exclusively as a noun for a golden age. 'The heyday of jazz.' 'The heyday of the Roman Empire.' The exclamation is extinct. What was once a spontaneous cry of delight has calcified into a historical marker for things that are already over.

Heyday carries a built-in elegy. You can only identify a heyday after it has passed. No one living through a golden age calls it that—the label is always applied in retrospect, by people who arrived too late.
The word's secret is in its origin: it was once a shout of pure present-tense joy. Now it only describes the past. Something alive became a headstone, and we use it to mark the graves of eras we wish we had witnessed.
