   Format: MarkdownItexEntry to fill in some of the ideas from a poset viewpoint. Note the use of the term 'residual' for the left adjoint. It seems that this use is really traditional coming from the sense that a 'residue' is the bit left ove. The link with `internal homs' is then a categorication of that, which puts a different light on internal homs! <a href="https://ncatlab.org/nlab/revision/residuated+morphism/1">v1</a>, <a href="https://ncatlab.org/nlab/show/residuated+morphism">current</a>
