A full stop marks the end of a sentence and it is also used after an abbreviation. If you abbreviate words such as "Avenue" to "Ave.", then don't forget the full stop! You'd be surprised how many people forget about the full stop, given its importance in a sentence.
This tricky quiz tests your ability to use full stops correctly, not only to show where sentences end, but also to mark abbreviations. The reason this is more difficult than it would appear is because abbreviation rules are not exactly straightforward and also vary between countries. In the UK (or U.K.), abbreviations which begin and end with the same letters as the word being abbreviated do not have a full stop. Therefore, "Mister" is abbreviated "Mr" (although you will very often see "Mr." being used), but "Honourable" is abbreviated "Hon." The rules are not consistent, though, because "Right Honourable", which you might think should be "Rt Hon.", according to the rules, is sometimes "Rt. Hon." and sometimes "Rt Hon". And both MP and M. P. are correct! As are U.S.A. and USA....Confused yet?See how good you are at spotting full stops in this quiz.
