Question asked in GTU Examination  subject: English(3110002) chapter: word formation (winter 2018)   Q.explain clipping word-formation process and compare its type by giving examples.[03] Ans: Clipping: Clipping is the word-formation process in which is reduced or shorted without changing the meaning of the word. or it's process of forming a new word by clipping off part of an existing word . Types of clipping: Clipping comes in four basic varieties: 1 . back Clipping: Back clipping is to take away the end of a word. like exam from examination .    examples: Ad form Advertisemen t, memo from memorandum. gym from gymnasium. math form   mathematics, lab from laboratory. 2 . Fore Clipping: fore-clipping is to remove the beginning of a word. like gator from alligator .       examples: varsity from university , phone from telephone . 3 .Middle Clipping:  Middle clipping is to retain only the middle of a word. like flu from influenza .    examples: shrink from headshrinker , tec from det...
