Help me understand the concepts to a newbie that just started

Greetings all,

So i just started investing 2 months ago, because i have money from a job now and stuff.

Now when browsing this subreddit everyone was calling each other regards, some times i understood it some times not.

To a newbie seeing something called a butterfly spread and 0dte are some godamn wizard spells.

When i was watching the clown show about SPCE i also learned of 2 new terms circuit breaker and dilution. Seems like i have a lot of holes since im just starting out and would like you guys to help me by giving a list of concepts so i can understand why most people in this sub are regarded.

Honestly the deepest deepest research i have done is just tax stuff in my country and i only know these terms :

\- options (kinda dont understand them even now) , dilution , circuit breaker, yahoo finance (being the free place for having the up to date price), what the bull/bear terms means and ETFS and dividend.

I'm probably missing a shiton of stuff so kindly link me to the resources only a great regard would know kindly :)
