What does rainiest mean?
Rainiest is the standard English superlative of rainy, meaning that something has or experiences more rain than any other thing in a comparison. It is normally used with places, periods, or conditions: a city can be “the rainiest in the country,” while a particular month can be described as “the rainiest of the year.” The word is an inflected form rather than an independent noun or verb, so it is not normally pluralized or used adverbially. In figurative descriptions, it can emphasize especially persistent bad weather, but its literal meaning is straightforward. Because “rainy” can refer both to measurable rainfall and to wet, overcast conditions, “rainiest” is especially natural in comparative statements about rainfall. Its concise superlative form makes it useful in weather reports, travel writing, and informal conversation, where it avoids the longer construction “most rainy.”

Where does rainiest come from?
The base word rainy ultimately comes from rain, whose English ancestor is Old English regn, related to forms such as German Regen and Dutch regen. English formed rainiest by adding the productive superlative suffix -est to rainy. Rainy and rainiest are therefore native English formations, while the underlying rain belongs to a wider Germanic word family.
How rainiest is actually used
Rainiest is normally used predicatively or after an article, as in “the rainiest place.” It can also function substantivally in phrases such as “the rainiest,” but it is not ordinarily used adverbially.
