Definitions:

Neap Tide

Lower-than-average high tides and higher-than-average low tides caused when the Sun’s gravity partially offsets the effects of the Moon’s gravity.

High Tide

The maximum height to which water in the ocean rises relative to the land in response to the gravitational pull of the Moon; also refers to the time when such high levels occur.

Low Tide

The lowest height to which water in the ocean drops relative to the land in response to the gravitational pull of the Moon; also refers to the time when such low levels occur.

Spring Tide

A condition of especially high and low tides caused when the sun, moon, and Earth are aligned, increasing the gravitational pull on the oceans.
