Etymology
Romanian borrowed "a demonstra" from French "démontrer" during the 19th-century modernization of the language, reinforced by the Latin source "demonstrare". The Latin word combines the prefix "de-" with "monstrare", meaning to show or point out. This makes it a learned addition rather than an inherited Latin word passed down through everyday speech.
