Abbreviation is the shortened form of a word or a phrase which can be used in place of that particular word or phrase.
Examples are: Lt for lieutenant, Hon for Honorable, Dr for doctor and St for Saint.
In British English full stops are not placed at the end of abbreviations that contain the first and last letters of the full expression. Examples are: Lt and St
In American English, full stops are placed after the abbreviations. Example: Dr., St. and Mr.
An abbreviation is usually pronounced like the original word or phrase, i.e. abbreviations don’t have the pronunciations of their own: Lt is pronounced as ‘lieutenant’ and ‘Hon’ as ‘Honorable’. However, there are some exceptions to this rule. For example, the abbreviation “e.g.” is pronounced as “For Example” against its full form which is “exempli gratia.”
An acronym is a word formed from the initial letters of the original words in a phrase. For examples: UNICEF, AIDS and RAM . An acronym is usually pronounced as a word and it carries the same meaning as the original phrase.
UNICEF for United Nations Children’s Education Fund
AIDS for Acquired Immuno Deficiency Syndrome
RAM for Random Access Memory
LASER for Light Amplification by the Stimulated Emission of Radiation
NATO for North Atlantic Treaty Organization
An initialism is a word formed from the initial letters of the original words in a phrase. It is constructed in the same way as an acronym but cannot be pronounced as a word. Examples are:
ATM for Automated Teller Machine
DVD for Digital Versatile Disk
LCD for Liquid Crystal Display
BBC for British Broadcasting Corporation
UNO for United Nations Organization.
