The period (or full stop) is an important punctuation mark in English that actually has three different uses: ending a sentence, indicating abbreviations, and other stylistic uses.

In the above example sentence there are many words which have been shortened to abbreviations in a number of ways. The following rules will tell you whether or not a period is needed with different types of common abbreviations.

The Punctuation Rules for Indicating Abbreviations

Word abbreviations are shortened versions of the original for purposes of efficiency. There are two kinds of abbreviations:

1. Abbreviations for multiple words phrases. These are made up of the first or few first letters of each word in the original phrase. They can be pronounced as:

-A series of the individual letters
NBC, KGB, IBM, LSD, TM, U.K.

-An acronym, in which the letters are pronounced as one word.
UNICEF, NATO, ANOVA

2. Abbreviations for single words. Usually pronounced as one word and can consist of:

-the first few letters of a word
Avenue - Ave., January - Jan.

-the first and last letter of a word
Mister - Mr., foot - ft.

-any combination of letters
Boulevard - Blvd., Route - Rte.

-the first letter of the word
Fahrenheit F, University - U.

-letters not in the original word
number - no., pound - lb., ounce - oz.

Use of a period in abbreviations

English, as any language, is evolving. Has English not now evolved to the point where the period after Mr, for example, is no longer necessary? Also, I was taught that the punctuation used in abbreviations (sometimes a "'") should be used in the position from which letters had been removed, so that there should NOT be a period after Mr, whereas there SHOULD be a period after ave (as in avenue).
Are you able to tell me where one can find the DEFINITIVE rules on use of punctuation in abbreviations, please? Perhaps, instead, you could confirm that there is no such thing and that the rules are just opinions held by certain people - if so, could you please tell me who these people are?
Thank you.
