The word "more undoubtful" is not a commonly used term in English. In fact, it is unclear what the intended meaning of this phrase could be, as it is not grammatically correct. However, if we examine the spelling of the word "undoubtful", we can see that it is pronounced /ʌnˈdaʊtfəl/, with the stress on the second syllable. This is a variation of the more commonly used "undoubted", pronounced /ʌnˈdaʊtɪd/. Both words mean "without doubt" or "certain".
There seems to be a misunderstanding, as the phrase "more undoubtful" does not have a commonly accepted definition in the English language. "Undoubtful" itself is not a widely recognized term but can be assumed to be the opposite of "doubtful," meaning something that is certain or without doubt.
If we were to analyze the words independently, "more" is a comparative adverb used to signify an increase in degree or quantity, while "undoubtful" is an adjective indicating something that is free from uncertainty or lack of conviction.
However, joining these two words, "more undoubtful," does not create a familiar phrase with a standard meaning. It is possible that it could be a creative and inventive way to emphasize certainty, confidence, or unwavering belief in a subject or statement. Nevertheless, without specific context or established usage, it is difficult to provide a precise definition.
