A DASH is a punctuation mark that is used to indicate a break in a sentence or a pause in speech. It is represented by two hyphens, and is sometimes referred to as an 'em DASH' or a 'long DASH'. The term 'DASH' can also refer to a short burst of speed, such as in the case of a SPRINT. In this context, it is often used in combination with other words, such as 'tach' (short for tachometer) and 'ofsalt' (short for offsalt).
