nämlich

In other words. Used to introduce a clarification, simplification, or explanation.

How to use

The adverb nämlich has two functions: as an explanatory particle/adverb meaning 'namely / specifically' (Ich habe zwei Hobbys, nämlich Lesen und Laufen), and as a causal particle/conjunction meaning 'because / you see / for' which never stands at the beginning of a clause; it always occupies position 3 or 4 inside the sentence (Er kam zu spät, er hatte nämlich den Bus verpasst — He came late, for he had missed the bus). Note: the source metadata mistakenly lists this as a verb, which is a major error; it is an adverb.
