Many words in English are based on the same root words, and knowing what these mean can help with spellings.
The roots 'scribe' and 'script' come from the Latin word for writing.
Usually, 'scribe' is used for verbs while 'script' is used for nouns.
The word 'scribe' itself, however, is both a verb and a noun. It means 'to write' and also refers to a person who was employed to make copies of documents before printing was invented.
