wärmeren

Wärmeren is the plural inflected form of the German adjective warm in the comparative degree. The base form is warm; the comparative is wärmer. In plural contexts, adjectives take the ending -en after definite articles or other determiners that signal weak declension: die wärmeren Tage, den wärmeren Temperaturen, mit den wärmeren Tagen. Without a definite article, the strong declension in plural yields wärmere: warme Tage, wärmere Temperaturen. This distinction is a standard part of German adjective declension and affects article–noun phrases in all cases.

Etymology and formation: warm derives from the broader Germanic word for heat, and the comparative form is created with the suffix -er. The -en ending on wärmeren reflects its role as a plural adjective in weak or mixed declension after definite determiners.

Examples: Die wärmeren Tage laden zu Spaziergängen ein. Wir erwarten im Frühling wärmere Temperaturen.

Notes: Wärmeren is not a verb form and does not express an action. It is an inflected adjective used to describe plural nouns in the comparative sense of warmness.
