The spelling of the word "more unprepossessed" can be explained using the International Phonetic Alphabet. The first syllable "more" is pronounced as /mɔːr/, with the long o sound, followed by the r sound. The second syllable "un" is pronounced as /ʌn/, with the schwa sound, followed by the n sound. The third and fourth syllables "prepossessed" are pronounced as /pri:pəzest/, with the long e sound, followed by the p sound, the r sound, and the s sound. Overall, the word is pronounced as /mɔːr-ʌn-pri:pəzest/.
The word "unprepossessed" is derived from the combination of the prefix "un-" (meaning "not") and the adjective "prepossessed".
"Prepossessed" comes from the verb "possess" with the prefix "pre-", meaning "before" or "in advance". The word "possess" comes from the Latin "possidere", which consists of "potis" (able) and "sedere" (to sit).
When "un-" is added to "prepossessed", it negates the meaning, so "unprepossessed" means "not prepossessed" or "not biased".
The inclusion of "more" before "unprepossessed" implies a higher degree of being "not biased" or "less influenced", suggesting an increased level of objectivity or impartiality.
