the word 'tagliatelle' is a direct borrowing from italian, entering english in the early 20th century. it is the plural form of the italian 'tagliatella', which is a diminutive of 'tagliata', meaning 'a cut'. this, in turn, derives from the verb 'tagliare', meaning 'to cut', which has its roots in the late latin 'taliare', from latin 'talea' meaning 'a cutting' or 'a rod'. the name perfectly describes the pasta's form, as it is made by cutting a sheet of dough into long, ribbon-like strips. the word's journey reflects the culinary influence of italy and the direct adoption of a descriptive term for a specific food item.
