tide Scientific  

/ tīd /

1. The regular rise and fall in the surface level of the Earth's oceans, seas, and bays caused by the gravitational attraction of the Moon and to a lesser extent of the Sun. The maximum high tides (or spring tides) occur when the Moon and Sun are directly aligned with Earth, so that their gravitational pull on Earth's waters is along the same line and is reinforced. The lowest high tides (or neap tides) occur when the Moon and Sun are at right angles to each other, so that their gravitational pull on Earth's waters originates from two different directions and is mitigated. Tides vary greatly by region and are influenced by sea-floor topography, storms, and water currents.

2. See also ebb tide flood tide neap tide spring tide

Etymology

Origin of tide¹

First recorded before 900; Middle English, Old English tīd “time, hour”; cognate with Dutch tijd, German Zeit, Old Norse tīth; akin to time

Origin of tide²

First recorded before 1000; Middle English tiden, Old English tīdan; see betide

Explanation

The tide is the daily rise and fall of the sea level. You can count on the regular changing patterns of the tide, unless of course a tsunami is headed your way. In a figurative sense, tide can mean a rising swell of support or unified feeling about a certain opinion or topic. So you may surf at high tide but also enjoy the rising tide of enthusiasm about surfing. If there is a wave of anything — immigration, inflation, terror — it can be referred to as a tide. No surfboards can navigate those tricky waves.
