一般的词典上会有同样的解释：
scrawl：to write or draw hastily or carelessly（匆忙而潦草地写、潦草地画）
scribble: to write or draw hastily or carelessly（同样的解释）
事实上，它们常常可以换用：
e.g., She scrawled / scribbled a quick note on the pad before leaving.
再如：
e.g., Don’t scrawl / scribble on the wall.
I scribbled / scrawled his phone number in my address book.
但要仔细区分的话，前者往往指有意去写，但结果写的不好或者写的潦草（intended to write something but has poor handwriting）；后者常常指写的内容可能是杂乱无章或毫无意义（to describe a random pattern with no meaning），比如：
- The boy scrawled on a piece of paper. (男孩在纸上潦草书写)
- The child scribbled on a piece of paper. (小孩在纸上乱涂乱画)
