Abbreviation
An abbreviation is a shortened form of a word or phrase that retains its meaning by omitting letters, sounds, or words.
Initialism: A shortened form made from the initial letters of words, pronounced as separate letter names. It shortens a phrase to its initials, as in “BBC.”
Texting abbreviations: Short forms used in text messages and online communication, such as “BRB” and “IDK.” Digital messaging favors compact forms that can be typed quickly.
Symbol: A mark or sign that represents an idea, object, quantity, or operation. Some symbols are compact representations, but are not shortened spellings of words.
Disambiguation: The process of distinguishing between multiple possible meanings of an expression. Context or expansion is needed when one abbreviation has several meanings.
Acronym: A word formed from the initial letters or parts of a phrase, usually pronounced as a word. It turns a phrase’s initials into a pronounceable word, as in “NASA.”
Medical abbreviation: A shortened form used in medical records, prescriptions, or clinical communication. Medical shorthand saves space but can create safety risks when ambiguous.
Apheresis: The loss of a sound or syllable from the beginning of a word over time. This historical sound change can resemble shortening without being a deliberate abbreviation.
Orthography: The conventional system for writing a language, including spelling, punctuation, and capitalization. Abbreviations follow and sometimes test a language’s writing conventions.
Contraction: A shortened form made by omitting internal letters or sounds, often marked with an apostrophe. It removes letters within a word or across words, as in “don’t.”
Abbreviation in legal writing: A shortened form used in statutes, legal documents, citations, or court writing. Legal documents use abbreviations under conventions that can vary by jurisdiction.
