Jakt ’hunting’ comes from Low German jacht. Jägare ‘hunter’ comes from Low German jeger. Both, and the Swedish verb jaga, have been created from the verb jagen ‘to hunt’, ‘pursue’, ‘chase’ from a Germanic stem *jahti-.
Of the same origin are English yacht and Swedish (lust-)jakt . Those are short forms for Low German jachtschip, ‘hunting ship’ ‘fast pirate ship’.
These hunters were lucky today.
