Morphology

megavolt = volt (transparent) = mega + volt

The meaning is a straightforward combination of the SI prefix 'mega-' meaning one million and 'volt' meaning the unit of electric potential.

Etymology

The word megavolt is made of mega-, meaning 'million' as in megabyte, and volt, the unit named after the scientist Volta. So a megavolt is literally 'one million volts', which is why it means a very large voltage.
