Back-formation
I. Definition
• Back-formation is an abnormal type of wordformation where a shorter word is derived by deleting an imagined affix from an already existing longer word in the vocabulary.

destruct ← destruction audit（审计）← auditor（审计员） spring-clean(大扫除)←spring-cleaning proofread（校对）←proofreader（校对者）
• In modern English, a number of backformation words have become the common core in the English vocabulary, such as aircondition, automate, beg, edit, televise, etc.
• D. There are a few nouns back-formed form adjectives. gloom ← gloomy greed ←greedy
• E. Many new back-formation verbs come from compounds: house-keep ←housekeeper sight-see ←sight-seeing daydream ← daydreamer

II.Back-formation & Clipping
• Both are the process of shortening in form, because they create shortened words from longer words.
• Clipping does not change the word-class and meaning of the original word, while backformation does.
