「殺很大」源於廣告、流行於網路，現在也時常用於日常生活，廣為年輕族群接受。現代漢語，本來不存在「殺＋很大」。「殺很大」起初以「殺」後加「很大」的結構方式出現，意指「打殺」激烈、「殺價」殺得很大或甚至價格「下殺」幅度大，為一「動詞」詞組。然而，在「殺很大」興起的同時，語意竟然開始有些許變異，其語法範疇亦有轉變。這種複合化歷程，經歷著句法結構「重新分析」（reanalysis）及語意的「諺語化」（idiomaticization），成為標準之「離心結構」（exocentric）。而此或正是「殺很大」，由不合語感、到合法、再到改造，一路「詞彙化」（lexicalization）過程。這樣的歷程，也許只是個開端，卻是個值得關注的「詞彙化」現象。本文從「分離」、「模糊」、「複合化」三階段探討聯合知識庫中113筆以「殺很大」作為新聞標題之語料的語意與其應用。經「重新分析」的「殺很大」一詞，由於語意擴大，看似任何語境皆能使用，但其實仍有規則可循。複合後的「殺很大」一詞意指「極致」，即：「某人事物有種極端之特質，或行為舉止有極端之表現，可以是正面的，亦可以是負面的」。因此，若能接受複合化之「殺很大」一詞為表現「極致」之語意，也就能接受各方面、各領域、表現極好或極壞皆使用「殺很大」一詞來描述。
