one-page

The compound adjective 'one-page' is a modern English formation that transparently combines two ancient roots. 'One' originates from the Proto-Germanic 'ainaz', which has cognates across Germanic languages and is ultimately from the Proto-Indo-European 'óynos', meaning 'single, one'. 'Page' entered English via Old French from the Latin 'pagina', which originally denoted a trellis or a fixed strip of land, later extended to a column of writing and finally a sheet of paper. The logic of the compound is entirely literal, directly applying the ancient concept of singularity ('one') to the later concept of a written sheet ('page') to describe a document confined to a single leaf.

Structure: one (single) + page (sheet) - one: From Old English 'ān' (one, a single). A numeral root indicating singularity. - page: From Latin 'pagina' (a sheet, a page, a column). A noun root referring to a leaf or sheet of paper.
