The spelling of the phrase "most hanged" may be confusing to some due to the irregularity of the past tense of the word "hang". In this case, "hanged" is used instead of "hung" because it is being used in a legal sense to refer to individuals who have been executed by hanging. The pronunciation of "most hanged" is /moʊst hæŋd/, with the stress on the first syllable and the "g" sound pronounced as a "d" due to the following "e" in the -ed ending.
The term "most hanged" is not commonly used and does not have a specific etymology as it does not form a common phrase or expression in the English language. However, it can be broken down into its constituent parts to understand the potential meaning.
The word "most" is a superlative form indicating the highest degree or quantity of something.
On the other hand, the word "hanged" is the past participle of the verb "hang", which means to suspend or attach by means of a rope or other cord.
Therefore, if we consider "most hanged" as a phrase, it could imply that the subject referred to has been hanged more than any other individual or group.
