lämpöinen

Lämpöinen is a Finnish adjective meaning warm in temperature or atmosphere. It describes something that has warmth, such as a warm day, a cozy room, or a friendly, welcoming mood. The term can be used literally about physical warmth and figuratively to convey kindness or a pleasant ambiance. It is formed from the noun lämpö (warmth) with the common adjectival suffix -inen.

In Finnish, adjectives have degrees. The positive form is lämpöinen; the comparative is lämpöisempi and the superlative is lämpöisin. Adverbs for warmth typically use other expressions, such as lämpimästi, while the adjective forms are used to describe nouns directly.

Usage notes and nuances: lämmin is more common in everyday speech for describing warmth, while lämpöinen tends to appear in descriptive writing or in slightly more formal or literary contexts. It can describe physical warmth (for example, a warm room or a warm day) and can also characterize an atmosphere or mood as being warm and inviting. Because Finnish speakers often prefer shorter, more everyday terms in regular conversation, lämpöinen may sound more distinctive or poetic in ordinary text.

See also: lämpö, which means warmth or heat, and lämmintä/lämpimästi for related forms and typical everyday usage. The contrast with kuuma (hot) and with lämmittämä (to warm) reflects the nuanced vocabulary Finnish uses to express different levels and kinds of warmth.
