Welcome to the forums.

The explanation of oscillators in general, and specific types is easily found using any search engine.

The idea is if you have a specific question about a design, post the schematic and ask the questions. Gives other people something concrete to discuss.

Oscillators oscillate because their output is connected to their input through a time delay and the active part has a net gain of more than 1.

That's it in a nutshell.

Next question?

Are you wondering where the signal comes from to start the feedback loop oscillating? Often this arises from transients when the power is first applied, but oscillators which depend on this may not always start reliably. Many good oscillators will start as a result of internal random noise, even if the power supply voltage comes on very gradually.
