The spelling of "un adroitly" is in line with the conventions of English spelling. The word "adroitly" can be transcribed phonetically as /əˈdrɔɪtli/, with stress on the second syllable. The addition of the prefix "un-" negates the meaning of the base word, resulting in a word with the opposite meaning. The pronunciation of the prefix remains the same as in any other word with the same prefix. Therefore, un adroitly is pronounced as /ʌn əˈdrɔɪtli/.
