Abbreviations and contractions are both used to shorten a word, but in different ways. · An abbreviation is formed using the initial letters (or sometimes other parts) of a longer word or phrase to represent the whole. Common examples include “Mr.” for “Mister,” “Dr.” for “Doctor,” and “NASA” for “National Aeronautics and Space Administration.” They are used in formal writing as well as everyday conversations. · A contraction, on the other hand, is formed by combining two words and omitting one or more letters. The deleted letters are replaced with an apostrophe (e.g., “cannot” becomes “can’t”

Contractions and portmanteaus are similar in that they are both formed by combining two words and omitting some letters. However, there is a difference between them: · Contractions usually combine two words that are often used together (e.g., “do not” becomes “don’t”). A contraction has the same meaning as its uncontracted form. · A portmanteau is formed by blending two words together to create a new word with a different meaning. For example, “brunch” is a combination of “breakfast” and “lunch.” This is also called a neologism.

Contractions are short words that are made by combining two words. This is often done by deleting certain letters and replacing them with an apostrophe (e.g., “do not” becomes “don’t”). · Although contractions are common in everyday speech, they should generally be avoided in formal or academic writing. However, there are exceptions (e.g., when writing dialogue in a story or directly quoting an author who uses contractions in your paper). · A good rule of thumb is to consider your audience and the intended effect of your writing when deciding whether to use contractions.
