A distinction is made between the 'spezielle Relativitätstheorie' (special theory of relativity) and the 'allgemeine Relativitätstheorie' (general theory of relativity). These adjectives are the most common words used with the term.
EXAMPLE
Die allgemeine Relativitätstheorie beschreibt die Gravitation als Eigenschaft von Raum und Zeit.
The general theory of relativity describes gravity as a property of space and time.
