Definition of the word scratch out

The phrase "scratch out" has multiple origins, depending on the context in which it is used. Here are three possible explanations: 1. Graphemic context: When we write something by hand and then cross it out or make a scratch mark through it, we say we're scratching it out. This usage is derived from the literal act of physically erasing or obliterating the written matter and has been in use for centuries. 2. Numeric context: In calculations, mathematicians use the term "scratch paper" to refer to blank sheets employed to perform rough calculations before transferring them to a sturdier medium such as a final draft or a permanent record. The expressions "scratch out" signify removing a figure from these working sheets, often to reinstate it with a different value or accurately record some determination. 3. Lexicographical context: A less common meaning of "scratch out" is to remove something from a list or a group by crossing out some entries or deleting them with a different method, which evolves from an ancient library cataloging technique. Then, archivists used scratchy knives or chisels to "scratch out " the recording, indicating taken-out accruals, reparation or overdue responsibilities. In any of these examples, "scratch out" implies elimination, cancellation, obliteration or erasure of an earlier written, calculated, or recorded form in replacement of a newer, more improved, or correct variant.
