Etymology
The compound 'high-tide' is a transparent combination of two native English words. 'High' originates from the Old English concept of physical elevation, while 'tide' originally meant a fixed time or season in Old English. The semantic narrowing of 'tide' to specifically refer to the cyclical rise and fall of the sea allowed the literal compound "high time of the sea" to emerge. This concrete meaning later provided a powerful metaphor, giving rise to the abstract sense of the peak or climax of any non-physical phenomenon, such as success or influence.
Analysis
Structure: high (elevated) + tide (periodic sea level change)
- high: From Old English hēah, meaning "tall, lofty, high." It is a Germanic root with a Proto-Indo-European origin (keuk-) related to bending or arching, which evolved to signify elevation.
- tide: From Old English tīd, meaning "point or portion of time, due time, period, season." Its Proto-Germanic root (tīdiz) is linked to time and division. In the context of the sea, its meaning specialized to the "periodic change of the sea level."
