What does wane mean?
Wane usually means to grow weaker, smaller, or less prominent over time. It is especially used for a gradual loss of power, influence, interest, intensity, or opportunity, as when a government’s popularity wanes or a funding programme begins to wane. The implication is usually that the decline is ongoing rather than sudden, which makes “wane” more measured than words such as “collapse.” In astronomy, the moon “wanes” when its visible illuminated portion decreases after the full moon. The verb can also function as a noun in literary or archaic constructions such as “the wane of his influence”; otherwise, it is a modern verb. Because it combines precise physical imagery with a broad moral and political sense, “wane” remains useful for describing processes that fade gradually but have not yet disappeared.
To decrease gradually in strength, size, intensity, or importance; also, of the moon, to show a progressively smaller illuminated portion.
"Support for the project waned once the initial excitement had passed."
The moon sense is standard astronomical usage. In general contexts, the word suggests a gradual rather than abrupt decline.
An archaic or literary noun for a decline or diminishing phase in strength, size, or importance.
"The novel charts the wax and wane of a friendship."
This noun is uncommon in modern English but remains recognizable, especially in formal or literary writing.
The plural is grammatically possible but rarely used because the noun sense itself is archaic and usually takes a singular.
"Successive wanes in public interest left the campaign without momentum."
The moon wanes, but the word comes from an Old English word for dwindling—not from the moon itself.

Where does wane come from?
Wane comes through Middle English from Old English wania, meaning “to dwindle” or “diminish,” with cognates in other Germanic languages. Its deeper roots are associated with the ancient Indo-European ideas of fading, withering, and lacking; Latin vanus, the source of vain, vanity, and ultimately vanish, belongs to the same broad etymological family. The noun sense developed from the verb during the early modern period and is now chiefly literary or archaic.
