Usage and nuance: Füllen describes making something contain a substance or material up to a desired level. It covers a wide range of contexts, from filling a bottle or a tank to filling a form or a space. Distinctions exist with related verbs such as ausfüllen (to fill out a form or questionnaire) and auffüllen (to refill or top up to capacity). In many everyday phrases, füllen emphasizes the action of adding content rather than the completion implied by filling up completed quantities.
