145+ Commonly Used Abbreviations Along With Their Details

Written by Pedro

An abbreviation is the reduced form of a word or phrase, such as alt. for altitude, a.m. for ante meridiem etc. The word abbreviation is abbreviated as abbr.–or, less commonly, abbrv or abbrev. We use those abbreviations in our daily life to save our some seconds and make the words easier.

In American English, the period is used in numerous abbreviations (Dr., Ms.). Contrary to this, in British usage of the period (or full stop) is generally omitted in abbreviations and first and last letters of the single word are used (Dr, Ms).  When an abbreviation comes at the end of a sentence, a single full stop (period) is utilized for both to mark the abbreviation and to close the sentence.
