Forms
pūrē (comparative pūrius, superlative pūrissimē, adjective pūrus)[1]
Etymology
It is from Latin pūrus (“clean, pure”) + -ē.[2][1][3] De Vaan traces pūrus to Proto-Italic *pūro- (“pure”) and Proto-Indo-European *ph₂ú-ro- (“clear, cleansed”), cognate with Old Irish úr (“green, fresh”) and with Sanskrit पुनाति (punā́ti, “cleans”).[4]
Earliest recorded meaning
Köbler dates it from Plautus,[3] who in the Aulularia has someone told to wash the vessels clean inside, and in the Asinaria uses it of nights spent chastely.[2]
Semantic evolution
Its first sense is cleanly, so as to be clean.[2] In religion it means with ritual purity: Cicero says that worship must be offered to the gods purely and chastely.[2] Of a way of life it means innocently, uprightly, as in Cicero's calm old age after a life lived quietly, purely and elegantly,[2] and of sex, chastely, as in Plautus.[2] It also means with a clear, bright surface: Horace speaks of Glycera's beauty shining more brightly than marble.[2] Varro uses it of words arranged neatly,[2] and of style it means plainly and clearly: Cicero has a case pleaded without display, plainly and lucidly.[2] It also means genuinely or perfectly, as in Horace's question of what brings true peace of mind,[2] and in law unconditionally, as in Gaius.[2] The OLD also records a form pūriter.[2]
