OED 還指出，“許多以 scr- 開頭的英語單詞在意義上或多或少地與其他單詞相符，這些單詞只因缺少初始的 s 而在形式上有所不同”（例如 crunch/scrunch， scringe， cringe 的另一種形式等）
It does not appear that these coincidences are due to any one general cause ..., but it is probable that the existence of many pairs of synonyms with scr- and cr- produced a tendency to change cr-, in words expressive of sounds or physical movements, into scr- so as to render the word echoic or phonetically symbolic.
