What does foliate mean?
Foliate is a formal verb meaning to decorate an object with leaves or leaflike ornamentation, and, less commonly, to produce or put forth leaves. Its natural home is the specialized vocabulary of architecture, sculpture, and metalwork: a stonemason may foliate a capital, and a goldsmith may foliate a border with scrolling vine patterns, work often described by the related adjective 'foliated' or the noun 'foliation'. In botany, the verb describes a plant coming into leaf. Derived from the Latin folium, meaning leaf, foliate shares its root with familiar words such as foliage, folio, foil, and defoliate. Because it belongs largely to technical and scholarly registers, it rarely appears in casual conversation, but it precisely names a decorative tradition that runs from medieval Gothic tracery to Victorian revival design. For readers interested in art and architecture, foliate offers a compact way to describe one of ornament's oldest and most enduring impulses: making stone and metal bloom.

Every carved Green Man peering from a medieval cathedral owes his leafy crown to the same Latin root as your book's folio numbers: folium, the leaf.

Etymology of foliate
Foliate comes from the Latin folium, meaning leaf, entering English around the early seventeenth century. It was formed on the same stem that produced the older English borrowings foliage (via Old French) and folio, and its ornamental sense reflects the long tradition of leaf carving in classical and Gothic architecture. Related coinages such as defoliate, foil, and trefoil all descend from this single Latin root.
