Pronunciation: [mˈɔː dˈʌbə͡ld] (IPA) 
The spelling of "more doubled" can be a bit confusing because of the pronunciation of the word "doubled." It is pronounced with a silent "e", as /ˈdʌbəld/. Therefore, when adding "more" to "doubled," we do not need to double the "e" as we would in other similar words, such as "troubled" or "wobbled." The correct spelling is "more doubled," without any additional letters added to "doubled" despite the long vowel sound.
"More doubled" is a comparative term used to describe a greater increase or multiplication of something already doubled. It refers to amplifying or intensifying a quantity or value that is in a twofold state. The term combines the idea of doubling, which means multiplying by two, with the comparative term "more," indicating a further increase or augmentation.
In mathematical terms, when a quantity is doubled, say "x," it becomes 2x. However, if we apply the concept of "more doubled," it implies multiplying the quantity again by two, resulting in 4x. Therefore, "more doubled" signifies a multiplication that exceeds the original doubling by an additional factor of two, leading to exponential growth.
This term is frequently used in various contexts. For instance, in finance, if an investment initially doubles, and then experiencing an additional growth that doubles it again, we can say the investment is more doubled. Similarly, in scientific studies, if a particular substance's concentration is doubled and then undergoes a further increase that doubles it one more time, we can refer to it as being more doubled.
Overall, "more doubled" characterizes a compound increase or multiplication that surpasses the initial doubling, signifying a considerable augmentation or amplification of a quantity or value.
The term "more doubled" does not have a specific etymology because it is not a commonly used phrase or word. "More" and "doubled" are separate words that have their own respective origins.
"More" comes from the Old English word "māra", which means "greater" or "additional". It can be traced back to the Proto-Germanic word "*maizô". The word has undergone various transformations in different languages over time but has retained a similar meaning.
"Doubled" is the past participle form of the verb "double", which derives from the Old French word "doubler", meaning "to double". It can be traced back to the Latin word "duplus", which also means "double" or "twofold".
