Definition
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Etymology
From minerals such as chlorite, serpentine, and epidote, and platy minerals such as muscovite and platy serpentine which are green in color
From English clay and stone as the rock contains more amount of clay

Formation
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
