You haven't said a weapon so I'll just give you some generic tips.
First step in any fight against a new monster is to learn how to not get hit. So spend maybe 5 minutes just dodging the attacks. It's very easy if you don't draw your weapon because you can sprint. Learn the attacks see where you can stand and how long the monster takes to recover.
Once you can manage to not get hit by the monster for minutes at a time, start drawing your weapon and trying to get some hits in during the gaps in attacks you've already noticed. This will be easy with quicker weapons, but should help with any weapon. Great sword would be the hardest to figure out.
In general that's how you fight any monster, learn the attack patterns and hit during the gaps and weaknesses of their attacks.
If you want specific weapon or monster advice I can provide that as well.
There's also many items that can be useful in a hunt, base World flash bombs are super op against anything that flies.
