zenith \ZEE-nith\, noun:
1. A highest point or state; culmination.
2. The point on the celestial sphere vertically above a given position or observer. Opposite of nadir.
The source of zenith is an error in transcription by ancient scribes. The M in the Arabic samt, “road,” was mistaken for an N, resulting in a Middle Latin senit.
Andrew Parsons ate a slightly overripe persimmon that sent his taste buds to the zenith of pleasure. It was subtly sweet, juicy, and slightly erotic.
