Back formation
The back formation method is exactly the opposite of the affixation method. The affixation method borrows this suffix to form the heart word, while the back formation method removes the misunderstood suffix to form the word. New words. For example: televise is the reverse of television by deleting -ion.
The new words created using this word-formation method are called reverse words. Most retromorphic words are verbs, and the most common protoform words that form retromorphic words are nouns and adjectives.
a. Noun-gt; verb. For example:
--pedlar à peddle (peddling)
--swindler à swindle (fraud)
b. Adjective -gt; verb. For example:
--peevish à peeve (angry)
--gloomy à gloom (becoming gloomy)
British English more often uses reverse word formation:
For example, the verb derived from the word burglar becomes burglarize in American English, and becomes castle in British English.
