Shortened forms of words like automobile (auto), examination (exam), mathematics (math),common in conversation and informal writing, are usually used in their entirety in formal contexts. These shortened words are called clippings.

Sometimes a clipping drives out its longer original and becomes a standard word in its own right.

 

Back-Clipping When back-clipping occurs, the beginning of the word is retained

Fore-clippingWhen fore-clipping occurs, the end of the word is retained

Back-and-Fore-ClippingWhen back-and-fore-clipping occurs, the middle of the word is retained
