Pronunciation: [mˈə͡ʊst ɐɡˈɪn] (IPA) 
The spelling of the word "most agin" may seem confusing at first, but it can be explained through the International Phonetic Alphabet (IPA). The word is pronounced /moʊst əˈɡɪn/, with the "o" sound in "most" followed by a schwa sound in "a". The "g" in "agin" is pronounced like a hard "g", while the final "in" is pronounced like the word "kin". This Southern American dialect term means "most against" or "strongly opposed to".
"Most agin" is an informal phrase commonly used in dialects of English, particularly in the Southern United States. The phrase consists of two components: "most" and "agin," which are both slang terms.
The term "most" in this context is an intensifier used to emphasize the degree or extent of something. It is used to convey a sense of emphasis, with a similar meaning to "very" or "extremely."
The term "agin" is a colloquial contraction of the word "against." It is often utilized as a dialectal variant of the standard English word, particularly in Southern dialects. It conveys the notion of being opposed or resistant to something.
Therefore, when combined as "most agin," the phrase conveys the idea of being strongly opposed or resistant to something. It implies a strong negative sentiment, disagreeing with or showing disapproval towards a particular idea, concept, person, or action.
For example, someone might say, "He's most agin any kind of change" to mean that the person strongly opposes any form of alteration or modification. The phrase is commonly used in casual conversations, storytelling, or in fictional representations to add color and authenticity to regional dialects. However, due to its informal nature, it may not be appropriate or widely understood in formal or professional contexts.
