praktizieren

Praktizieren is a German verb meaning to practice or to perform in practice. It denotes carrying out a profession, applying methods, or exercising a skill in real‑world situations. The term is commonly used to describe active professional work or the repeated application of techniques.

In professional contexts it refers to practicing a licensed occupation or field of expertise, for example medicine or law: “Sie praktiziert als Ärztin in München,” or “Er praktiziert seit zehn Jahren als Rechtsanwalt.” It can also describe the act of applying a technique or principle in real work, as in the sense of putting knowledge into action.

The noun form die Praxis is typically used for the practice as a concept, the office or clinic, and for the general notion of working in a profession. The nominalized verb das Praktizieren exists but is rarer and mainly found in formal or technical writing.

Etymologically, praktizieren is derived from the root related to Praxis (practice) with the suffix -izieren, combining notions of practical activity and application. The verb is regular in its conjugation: present tense ich praktiziere, du praktizierst, er praktiziert, wir praktizieren, ihr praktiziert, sie praktizieren. The past tense forms include Präteritum ich praktizierte and Partizip II praktiziert, with Perfect form ich habe praktiziert.
