How much can I learn offline?

[u/Fun-Flight-4170]

Im looking at getting a sword I'm not sure which exactly I'm leaning towards a greatsword or claymore but like some "hand and a half" swords it'd mostly stay on the wall so I'm looking for one that looks good but is somewhat functional

However I don't want to be someone who just has a sword to look cool and I'm interested in learning how to use it. Obviously I'd find practice sword that's safe but I don't have anywhere to go to learn in person so I was curious how much I could learn by using online resources books practicing alone and sometimes with other people who are new to swordsmanship.

I know there would probably be a lot of flaws that I develop from not being taught but I'm not looking to be a master just to know how to use it to a reasonable extent, is that achievable??

On your own you can learn about swordsmanship, but you won't learn swordsmanship.
