'magmatic' originates from the Greek word 'magma,' where 'magma' meant 'thick unguent or paste.'

'magma' was adopted into Latin as 'magma,' and eventually became the modern English word 'magma,' from which 'magmatic' is derived.

Initially, it referred to a 'thick paste,' but over time it evolved into its current meaning related to molten rock beneath the Earth's surface.
