Definition
Let $\struct {S, \odot}$ be a semilattice.
Let $\struct {S, \odot}$ have the property that every subset of $\struct {S, \odot}$ is a subsemilattice.
That is, such that every subset of $\struct {S, \odot}$ is closed under $\odot$.
Then $\struct {S, \odot}$ is known as a total semilattice.

Linguistic Note
The term total semilattice was invented by $\mathsf{Pr} \infty \mathsf{fWiki}$ in order to make the terminology more compact.
As such, it is not generally expected to be seen in this context outside $\mathsf{Pr} \infty \mathsf{fWiki}$.
