tuulisessa
Tuulisessa is an inflected form of the Finnish adjective tuulinen, meaning windy. In Finnish, adjectives decline to agree with the nouns they modify in case and number, so tuulisessa appears when the modified noun is in the inessive case, typically translated as "in the windy …" It is not a standalone word with a separate meaning; its sense is determined by the noun it describes.
Common usage occurs in phrases describing location or state, such as tuulisessa talossa (in the windy house),
Grammar and formation notes: tuulinen is formed from the stem tuuli (wind) with the adjectival ending -inen.
