Rounding out our discussion of cum clauses are the causal and concessive (or adversative). While cum often means "when", a cum clause can also show the cause of the main clause, and in this case we would translate cum as "since". And sometimes the cum clause operates in opposition to the main clause, often with a tamen, "still" in the main clause. In this case, we translate cum as "although". This video will discuss these two uses, and summarize all four types of cum clauses at the end.
