The spelling of "neap" can be tricky because its pronunciation doesn't match its spelling. The word is pronounced /niːp/ (nee-p) and indicates the lowest tides that occur around the time of the quarter moons. While the word is spelled with the letter "a," its vowel sound is actually pronounced as a long "e" sound. This is due to the influence of French, where "ea" is often pronounced as a long "e." So remember, even though it's spelled "neap," it's pronounced as "nee-p."
Neap, as a noun, refers to a type of tide that occurs twice a month when the difference between high and low tides is the smallest. Neap tides happen during the first and third quarters of the moon, when the gravitational pull of the sun and moon partially cancel each other out. This results in smaller tidal ranges than usual. Neap tides are characterized by waters that neither rise as high during high tide nor recede as far during low tide.
As an adjective, "neap" can describe something that is unimpressive, weak, or lacking strength. It often applies to small or insignificant objects or phenomena. For example, a neap breeze is a light and gentle wind that barely moves the air, lacking the strength to have any substantial impact. Similarly, the term can be used to describe a neap stream, which is a small and sluggish watercourse with a low flow rate.
In general, the term "neap" signifies something that is minor, feeble, or lacking vigor. It is primarily used within the context of tides and natural phenomena, but can also be extended metaphorically to describe other situations or objects that possess minimal force or effect.
Scanty; deficient; low; applied to the tides which occur about the first and last quarters of the moon, and which are called neap-tides; the spring-tides are the highest tides.

The word neap originated from the Old English word nep, which likely came from Proto-Germanic *nepuz. Its exact origins beyond Proto-Germanic are uncertain. In Old English, nep referred to the low tide, particularly the tide occurring after the first and third quarters of the moon, when the range between high and low tides is at its smallest. Over time, nep transformed into neep and eventually into neap.
