What is another word for most pitch dark?
Pronunciation: [mˈə͡ʊst pˈɪt͡ʃ dˈɑːk] (IPA) 
The phrase "most pitch dark" suggests a level of darkness that is nearly complete and impenetrable. To describe this level of darkness using synonyms, we might use phrases such as "utterly black," "profoundly dark," or "impossibly shadowy." Other options might include "inky," "murky," or "obscure." This kind of darkness is often associated with fear or mystery, so words like "spooky," "eerie," or "haunting" might also be appropriate. No matter which synonym we choose, the message is clear: this is a place where even the tiniest glimmer of light is hard to come by.
