rennende

Rennende is the present participle of the German verb rennen, meaning “to run.” It is commonly used as an adjective to describe something that is in motion or a person or animal that is running. The base participle is rennend, and when used attributively or predicatively it takes inflection endings according to gender, number and case. Common forms include der rennende Mann, die rennende Frau, das rennende Pferd (singular) and die rennenden Kinder (plural). With an indefinite article the forms are ein rennender Mann, eine rennende Frau, ein rennendes Pferd.

Rennende can also appear in phrases or clauses that describe ongoing action, such as Er rannte, rennend durch den Park. In everyday language German typically relies on simple tenses, but the participle is widely used in descriptive writing and in set phrases. The word is usually not capitalized when used as an adjective. A capitalized form would occur only if the participle were treated as a noun or name, which is uncommon for this particular usage. The formation follows the standard German pattern for present participles, built from the verb stem renn- with the suffix -d and then declined like an ordinary adjective.
