In Swedish, we use 'vika' in quite many ways:

vika - to reserve,
vika - to fold,
vika upp - to unfold,
vika ut - to expose,
vika av - to deviate,
vika undan - to deviate,
giva vika - to give way,
et cetera.

My favourite use of 'vika' is in the (religious) imperative "Vik
hädan!" ([Fiend] go away!)
