Here is a link to a website that has gathered a lot of the vocabulary of the various rooms in the house of philosophy: https://www.philosophybasics.com.
I would like to try, however, to change your perspective a little on the study, pursuit, and practice of philosophy. I would like to suggest that it is a way of life more than it is an interest or a study.
From an etymological standpoint, "philosophy" is the love of wisdom, but from a practical standpoint it is the relentless, systematic, impassioned, and kaleidoscopic catalogue of the attempts of humans to answer Thales' question: "What is all of this really?"
The study has been long, but fortunately, about two centuries after Thales began it, Socrates embodied it, and died for it, and Plato wrote a beautiful and brilliant series of dialogues that recorded and systematized Socrates' philosophy and much more.
Some of us think of philosophy as an umbrella for the inquiries of metaphysics, epistemology, and axiology. Others have different inquiries under the umbrella, perhaps ethics, theology, or physics.
I put all serious inquiry under the umbrella of philosophy and think of it as the inquiry into inquiry itself.
Philosophy is our way of trying to understand understanding, and everything else. Philosophy is the thing that homo sapiens sapiens do that no other species can.
Unless one is a committed mystic, who believes that everything can be understood in one insight, be it nirvana, Christ's Kingdom of Heaven, or a true view of Tao (the way), the path to real knowledge of this cosmos is long and very challenging. And words are the means by which we navigate that path, chronicle our navigation of it, and guide others along it. They are not impediments or obstacles in the path.
For us non-mystics, it takes a lot of words to express an understanding of the magnitude required to slake our intellectual thirst. Start a love affair with your dictionary and keep it by you as you explore the cosmos.
