Division of guitars by material which are made of

If we talk about the wood from which the body (corpus) of the instrument is made, we use the terms massive , semi-solid and plywood.

Massive (all-massive)

If we say about the guitar that it is massive, it means that the whole body was made of one piece of wood.

Polomasive (all-massive)

At least some part of the body (front plate, back plate, ...) was made of one piece of wood.

Plywood

Mostly several layers of wood (or laminate boards) are glued together.
