An Academic Look at HDTH

HDTH is an initialism abbreviation. Technically, this means it is pronounced using its individual letters (i.e., Aitch Dee Tee Aitch), but as this is harder to say than "How did that happen," it is not often said using its letters. In other words, the abbreviation HDTH is for efficiency in writing and not efficiency in speech.

HDTH plays the role of an interrogative sentence (i.e., a question), but it is commonly seen without a question mark. In other words, it can be written " HDTH?" or "HDTH".
