Usage tips
Word structure
The word is derived from 'der Begriff' (term, concept). The endings '-lich' and '-keit' together form an abstract noun that refers to the entire system of terms, not just to a single one.
EXAMPLE
Dieser Begriff ist in der modernen Physik sehr wichtig.
This concept is very important in modern physics.
Register and context
'Begrifflichkeit' (terminology) is a word used in specialist and academic language. It is used in academic discussions, for example in philosophy, law, or sociology, but almost never in normal everyday life.
EXAMPLE
Die exakte juristische Begrifflichkeit ist für einen Vertrag entscheidend.
Precise legal terminology is crucial for a contract.
Sentence structure and usage
The word is usually specified more closely by an adjective or the genitive to make clear which field is meant. Typical formulations are 'die philosophische Begrifflichkeit' (philosophical terminology) or 'die Begrifflichkeit der Quantenmechanik' (the terminology of quantum mechanics).
EXAMPLE
Für seine Masterarbeit musste er die Begrifflichkeit der Systemtheorie lernen.
For his master's thesis, he had to learn the terminology of systems theory.

Begrifflichkeit vs Vokabular
vocabulary
'das Vokabular' and 'die Begrifflichkeit' both have to do with words in a particular field. 'Vokabular' refers more to the words themselves: the vocabulary of a person, a language, or a subject area. 'Begrifflichkeit' sounds more specialized and means not only the words, but also how exactly they are understood and defined. The words can be confused when talking about specialized texts. If you are talking about the set of words, 'Vokabular' fits better. If it is about precise terms and clear meanings in a theory or discussion, 'Begrifflichkeit' is more accurate.
Begrifflichkeit
In dem Vortrag erklärt Herr Hoffmann zuerst die Begrifflichkeit, damit alle die Fachwörter gleich verstehen.
In the lecture, Mr. Hoffmann first explains the terminology so that everyone understands the technical terms in the same way.
Vokabular
