前綴per-(pel-,pol-,par-,pil-,por-)詞源、意思和例詞
前綴per-來源于拉丁介副詞per，它基本意思是“through（通過）”，由此又引申出具有加強意義的“throughout（貫穿）、thoroughly（徹底）”及含有貶義的to destruction（毀壞）等意思（表示貶義的per-只出現(xiàn)在少數(shù)單詞中，也就是表示貶義的per-派生出的單詞比較少）。per-除上面的意思外，還有“intensive,falsely, excessive, by, by means f"等含義。per-是原生前綴，主要與拉丁動詞詞干結(jié)合，構(gòu)成動詞及其相應的名詞或形容詞。
