"Does one ever know where one is going?"

[jdgomezm]

why Je? what is that!!!!

[Menschenkind]

It's an adverb! je and jemals describe the indefinite time aspect in 'ever' – Will you ever change? - Wirst du dich jemals ändern? – like, eventually, at any given time.

[AZhekova]

Weiß man je, wohin man geht?
Why is 'man' on the second place in 'wohin man geht'? Can't it be 'wohin geht man'?

[lingding]

no, 'wohin man geht' is the dependent clause in this sentence, and german sentence structure dictates that the verb goes at the END of dependent clauses.
