Before answering the questions I would like to give a short explanation of each word formation process:
1.- Prefix addition is when a prefix is added to a word to for a new word, for example: work----over we add the prefix over to form the new word overwork from the verb work.
2.-Suffix addition for example: work----er we add the prefix er to form the new word worker from the verb work.
3.- Compounding is s the word formation process in which two or more lexemes combine into a single new word. Compound words may be written as one word or as two words joined with a hyphen.
For example: dinning-table
4.- Telescoping (blending) is the process of merging parts of words into one word. For example : galumph gallop + triumph, or chortle chuckle + snort.
5.- Shortening or clipping is the word formation process which consists in the reduction of a word to one of its parts . Clipping is also known as "truncation". for example: maths from mathematics.
6.- Back formation is the process of forming a new word (a neologism) by removing actual or supposed affixes from another word. for example:
the verb burgle from the older English noun burglar.
Now let us answer the questions:
1 = compounding
2 = compounding
3 = prefix addition
4 = back formations
5 = prefix addition
6 = back formations
