betrifft

Betrifft is the third-person singular present tense of the German verb betreffen. It means to concern, affect, or be relevant to. It is used to say that something has bearing on a person or situation. Examples: "Dieses Gesetz betrifft uns alle" (This law concerns us all) and "Was mich betrifft, bleibe ich zu Hause" (As far as I’m concerned, I stay at home). The phrase "Was mich betrifft" is a common idiom for indicating one’s own point of view.

Grammatically, betreffen is a strong verb with the prefix be-, used inseparably. The infinitive is betreffen; the past tense is betraf; the past participle is betroffen. In the present, forms include er/sie/es betrifft and wir betreffen; the second-person forms are du betriffst and ihr betrefft. The constructions "Was X betrifft" or "Was X betrifft, Y" are widely used in both formal and informal language to introduce the part of a topic that concerns someone.

Der Betreff is a noun meaning the subject of a letter or email; it appears as the heading Betreff: [topic]. The adjective betreffend means "concerning" or "relevant to." The verb betreffen is common in official language, journalism, and policy texts to denote relevance or impact. Its basic meaning remains stable across contexts: to be of concern to someone or something, or to touch upon a matter.
