conjunction
as long as, while
B1
'solange' is a subordinating conjunction meaning 'as long as' or 'while'. It introduces a subordinate clause and typically sends the finite verb to the end in German word order. Used for duration or conditional sense (provided that). Comma separates the clause; not a preposition or reflexive verb.
