The phrase "hacking up" does not have a specific etymology on its own. However, the two words "hacking" and "up" can be examined separately for their origins.
1. Hacking: The term "hacking" is believed to have originated from the word "hacken" in Middle English, which meant "to cut or to chop". It later evolved to mean "to cough harshly or to clear the throat". The connection between these two meanings is unclear, but it may be due to the sound produced when someone coughs forcefully.
2. Up: The word "up" has Old English origins and has been used in the English language for many purposes. In the context of "hacking up", "up" is a preposition indicating direction or movement to an upper position, or in this case, a forceful action of expelling something from the throat or chest.
