Buddha (title)

Buddha (Sanskrit: बुद्ध) refers to one who has achieved enlightenment and Buddhahood, and has fully comprehended the Four Noble Truths. Contemporary, the term refers to Siddharta Gautama, the teacher and founder of Buddhism, who is simply known as "the Buddha". The term also refers to others who have achieved enlightenment and Buddhahood, such as the 27 Buddhas who preceded Gautama, Amitābha and the future Buddha, Maitreya.

The word Buddha means "awakened one" or "the enlightened one". "Buddha" is also used as a title for the first awakened being in a Yuga era. In most Buddhist traditions, Siddhartha Gautama is regarded as the Supreme Buddha (Pali sammāsambuddha, Sanskrit samyaksaṃbuddha) of the present age.
