Etymology
The word 'folio' has a direct lineage from the Latin 'folium', meaning 'leaf'. This term was adopted into Medieval Latin as 'folium' to refer to a leaf of paper or parchment in a manuscript. The transition from the literal meaning of a tree leaf to a sheet of paper is a classic example of semantic extension, drawing an analogy between the form and function of natural and man-made objects. The '-o' suffix stabilizes it as a noun in English, specifically denoting a format in printing and bookbinding where a sheet is folded once, creating two leaves, much like the two sides of a single leaf.
