Many of the words and terms essential to Buddhism are in the Pali or Sanskrit languages and have remained common derivatives from the original for centuries, even when speaking in other languages. These words often vary in spelling, as they have been transliterated from their original alphabets, so to understand Buddhist terms one must keep in mind that a word can appear in different forms.
Below, find an alphabetical list of essential words and key concepts in Buddhism. I will often give alternate spellings; learning these will save a lot of confusion later!
