The word 'Veda' is derived from the word ‘Vid’ which means ‘to know’.
The four Vedas are- the Rigveda, the Samaveda, the Yajurveda, and the Atharvaveda. Among these, the RigVeda is the oldest and believed to be composed during the early 1500 BCE. It contains hymns that were written in praise of various gods and deities seeking their support.
The Samaveda is the veda of chants, meaning sweet songs. It was a guide for the priests who used to sing the hymns while performing the yajnas.
