The question is that write everything about the words formation process

Here are some of the main word formation processes:

Derivation: This involves adding affixes (prefixes or suffixes) to existing words to create new words, often changing their grammatical category. For example, adding "-ness" to "happy" creates "happiness," or adding "un-" to "happy" creates "unhappy."

Compounding: This process combines two or more existing words to form a single new word. The meaning of the new word is often related to the meanings of its components. Examples include "sunflower" (sun + flower) or "blackboard" (black + board).

Conversion (or Zero Derivation): This occurs when a word changes its grammatical category without any change in its form. For instance, the noun "access" can be used as a verb ("to access a file"), or the verb "to run" can be used as a noun ("a long run").

Clipping: This involves shortening a longer word by removing one or more syllables, while retaining its core meaning. Common examples include "phone" from "telephone," "flu" from "influenza," or "exam" from "examination."

Blending: This process combines parts of two words to form a new word, often taking the beginning of one word and the end of another. The resulting word typically carries a meaning related to both original words. Examples are "smog" (smoke + fog) and "brunch" (breakfast + lunch).

Acronymy: This involves forming a new word from the initial letters of a series of words. These can be pronounced as a single word (e.g., "NASA" from National Aeronautics and Space Administration) or as individual letters (e.g., "FBI" from Federal Bureau of Investigation).
