5- Affixation: the process of adding one or more affixes to a root, it covers prefixation and suffixation. For example, the word "reusable" has a prefix and a suffix: "re-" is the prefix and "-able" is the suffix.
6- Blending: is the most creative way in word formation, where speakers take two words and combine them based on the sound structure and not on morpheme structure. Blending words has a number of methods, for example: the word "brunch" its method was by taking the beginning of the word "breakfast" and the end of the word "lunch" to form the word "brunch" which refers to a late morning/early afternoon meal. This is the most common method of blending.
7- Acronyms: are words formatted by taking the initial letters of a phrase (sentence) and making a word out of it. For example: "NASA: The National Aeronautics and Space Administration", "CELTA: Certificate in English Language Teaching to Adults" and so many examples.
8- Clipping: (Marchand, 1969) "Clipping is the word formation process which consists in the reduction of a word to one of its parts". In another form, clipping is known as "shortening words". There are four types of word clipping:.
• 8.1 - Back clipping: it's the most common type, where the beginning is saved, for example: "ad: advertisement", "gas" gasoline", "math: mathematics" and so on.
• 8.2 - Fore-clipping: it keeps the final part of the word. For example: "phone: telephone", "coon: raccoon" and so on.
• 8.3 – Middle clipping: it saves the middle part of the word. For example: "flu: influenza" etc.
• 8.4 – Complex clipping: clipped forms are also used in compound. One part of the original compound most often remains intact. For example: "cablegram: cable telegram" (Yousefi, 2009).
