cieplnymi

Cieplnymi is the instrumental plural form of the Polish adjective meaning related to heat or thermal. In correct Polish orthography, the adjective is cieplny or ciepłny depending on form, and its instrumental plural for masculine personal nouns is cieplnymi (with diacritics: ciepłnymi). The form cieplnymi appears in ASCII texts as a non-diacritic variant.

In usage, cieplnymi describes nouns in the instrumental case, typically referring to tools, processes, or phenomena connected with heat. Examples include narzędziami cieplnymi (with thermal tools), procesami cieplnymi (thermal processes), or zjawiskami cieplnymi (thermal phenomena). The pattern follows standard Polish adjective declension, where the instrumental plural ending for masculine personal and many inanimate nouns is -nymi.

Etymology and relation to other terms: the base is the root related to heat, from words such as cieplo (heat) and cieplny (thermal, heat-related). The suffix -ny forms adjectives, and -nymi marks instrumental plural. The diacritic form ciepłnymi is the typical standard in Polish; cieplnymi is the common ASCII rendering used when diacritics are unavailable.

Summary: cieplnymi is not a separate lexical entry but a grammatical form used to describe heat-related nouns in the instrumental plural. Its proper spelling with diacritics is ciepłnymi; in plain ASCII texts it appears as cieplnymi.
