With citations explain the following 1)back formation 2)coinage?

1) Back formation is a process in linguistics where a new word is created by removing an affix from an existing word. This can happen when speakers mistakenly interpret a word as having an affix when it does not. For example, the word "editor" was formed by removing the suffix "-or" from the word "editorial." Back formation can also occur when a word is shortened and then re-analyzed as a base form. An example of this is the word "burgle," which was formed by back formation from the word "burglar."

2) Coinage is the process of creating a new word or phrase that did not previously exist in a language. This can happen through a variety of means, such as blending two existing words together (e.g. "brunch" from "breakfast" and "lunch"), borrowing a word from another language (e.g. "sushi" from Japanese), or creating a completely new word based on sound or meaning (e.g. "googol" coined by mathematician Edward Kasner).
