The spelling of the phrase "most gladdened" can be confusing due to the variety of English phonetics. Using the International Phonetic Alphabet (IPA), we can break it down. "Most" is pronounced /moʊst/ with a long o sound, while "gladdened" is pronounced /ˈɡlædənd/ with a short a sound. Together, the phrase is pronounced /moʊst ˈɡlædənd/. While the word "gladdened" is not commonly used in modern English, it means to make someone feel happy or delighted.
The word "most gladdened" does not have a direct etymology, as it is a combination of two separate words: "most" and "gladdened".
"Most" is derived from the Old English word "mǣst", which means "greatest" or "to the greatest extent". It is related to the Old High German word "meist" and the Gothic word "maists".
"Gladdened" is derived from the Old English word "glædian", which means "to make glad" or "to rejoice". It is related to the Old Norse word "gladda" and the Gothic word "gladjan".
Therefore, when combined, "most gladdened" suggests the highest or greatest level of being made glad or rejoicing.
