There are also so-called combined verbs, which are created by suffixing certain verb stems (like "bil" or "ver") to the original stem of a verb. "Bil" is the suffix for the sufficiency mood. It is the equivalent of the English auxiliary verbs "able to", "can" or "may". "Ver" is the suffix for the swiftness mood, "kal" for the perpetuity mood and "yaz" for the approach ("almost") mood. Thus, while "gittin" means "you went", "gidebildin" means "you could go" and "gidiverdin" means "you went swiftly". The tenses of the combined verbs are formed the same way as for simple verbs.
