Questions & Answers about Abends ist das Fernsehen oft langweilig.
Abends here is an adverb meaning “in the evenings / at night in general”, not a full noun phrase.
Adverbs do not take an article or a preposition, so you simply say abends, not am Abend.
Am Abend is also possible, but it usually points to a more specific evening or time frame, while abends sounds more like a general habit.
- abends = in the evenings (generally, repeatedly, as a habit)
- Abends sehe ich oft fern. – I often watch TV in the evenings.
- am Abend = in the evening (more like one particular evening or one time period)
- Am Abend sehe ich heute fern. – I’ll watch TV this evening.
In practice, they can overlap, but abends strongly suggests a regular, repeated situation.
