After finishing the Dutch course tree, I am now using this mirror course to continue learning Dutch. In quite a few sentences that contain "leave", I have noted that some of them use the verb "verlieten" but others use "vertrekken". And the other is not accepted. Would somebody please explain when "verlieten" should be used and when "vertrekken"? Thanks a lot.
'Vertrekken' is used in combination with 'van', while'verlieten' is used without 'van'.
'I left him' - 'Ik verliet hem'
'I left the airport' - 'Ik vertrok van de luchthaven'
