Pronunciation: [mˈə͡ʊst bɹˈe͡ɪɪŋ] (IPA) 
The spelling of the word "most braying" can be explained using the International Phonetic Alphabet (IPA). "Most" is pronounced as /moʊst/, with the "o" sound like in "go" and the "t" sound at the end. "Braying" is pronounced as /breɪɪŋ/, with the "a" sound like in "ray" and the "y" sound at the end. Together, "most braying" refers to an animal's loud and harsh cry, like that of a donkey, which can be heard from a distance.
"Most braying" refers to the extreme or highest level of a particular sound or behavior associated with braying, which is the characteristic loud, harsh, and raucous vocalization made by donkeys. In this context, "most" indicates the utmost degree or intensity.
The adjective "braying" itself refers to the distinctive cry produced by a donkey, characterized by its loudness, coarseness, and sometimes grating quality. It is typically a prolonged and repetitive noise, often likened to a loud, brusque, and slightly nasal "hee-haw" sound.
When we refer to something as "most braying," we imply that it epitomizes or exemplifies the essence of this donkey-like vocalization, going beyond what is considered typical or ordinary. It can be applied metaphorically to describe sounds or behaviors that resemble the nature of a donkey's bray by being loud, strident, or grating.
The phrase "most braying" can also be used humorously or derogatorily to describe people or situations that display qualities reminiscent of a donkey's bray. It suggests a lack of refinement or subtlety, or even a level of obstinacy or annoyance. However, it is important to note that this phrase is typically used figuratively and should not be taken literally when referring to actual donkeys or their behavior.
The phrase "most braying" does not have a specific etymology as it is formed from the combination of two separate words: "most" and "braying". I will provide the etymology of both words individually:
1. Most: The word "most" originated in Old English as "māst" or "mǽst" and is related to Old Saxon "mest", Old Frisian "mest", and Gothic "mist". It ultimately derives from the Proto-Germanic word "maistaz" meaning "most, the greatest". The Old English form of the word gradually transformed into "most" through linguistic changes.
2. Braying: The word "braying" comes from the verb "bray" which dates back to Middle English.
