We all learned about punctuation marks in school, I hope. Punctuation marks such as the full stop to end a sentence. The comma to provide a little pause within a sentence, and help you digest what was said. The question mark to ask a question, such as where do I use a question mark? Exclamation mark! for indicating a strong feeling or higher volume when read aloud. I just learnt about two punctuation marks that I feel can be very useful and appropriate for a multitude of sentences.
‽ The Interrobang. The Interrobang combines an exclamation mark with a question mark, A sentence ending with an interrobang either asks a question in an excited manner or expresses excitement or disbelief in the form of a question. This would be equivalent to having a WTF at the end or beginning of a sentence but in a more refined eloquent way.
The Irony mark (؟) (French: point d’ironie) is a punctuation mark that purports to indicate that a sentence should be understood at a second level. It is illustrated by a backward-facing question mark. An irony mark may sometimes be referred to as an irony point, snark or zing. Its usage is extremely rare but I feel it could be very useful.
Sentences that you could use the irony mark in could be:
Life is short, then you die ؟
or, If love is blind, why is lingerie so popular؟
There are other punctuation marks that are underused but the Interrobang and Irony mark I find very appealing. Forget the LOL, BRB, WTF, ROFL,LMAO, and assorted smileys symbols and abbreviations that crept into the English language and use these instead to sound eloquent and kash5a :-)
