tidal
UK: ˈtaɪd(ə)l | US: ˈtaɪd(ə)l
adj. relating to or affected by tides
adj. occurring at regular intervals, like tides
The word "tidal" derives from the Old English "tīd" (meaning "time" or "tide") combined with the suffix "-al," which forms adjectives. Originally, "tide" referred to a period or season (e.g., "Christmastide"), but its meaning narrowed to the rise and fall of sea levels due to gravitational forces. The suffix "-al" (from Latin "-alis") signifies "pertaining to," making "tidal" mean "related to tides." The word reflects the natural rhythmic patterns of the ocean, linking time and cyclical movement.
