me too; I also
A formal or literary expression meaning 'me too' or 'I also'. The use of 私 (わたくし) is very formal; in casual speech, 私も (わたしも) or 僕も is more common.
私も又、その意見に賛成です。
I also agree with that opinion.
私も又、同じように感じておりました。
I also felt the same way.
A fixed phrase combining the formal first-person pronoun 私 (わたくし) with the particle も ('also') and the adverb 又 (また, 'again' or 'also'), literally 'I also again'. The exact historical derivation is uncertain, but it functions as a set expression for emphasis.
