expression, noun
my party; our party
Used in political or organizational contexts to refer to one's own party. The possessive 我が (わが) is formal/literary.
我が党はこの法案に反対します。
Our party opposes this bill.
彼は我が党の代表として演説した。
He gave a speech as a representative of our party.
pronoun
I; me; you (archaic)
Archaic pronoun usage. Sense 2: first person ('I/me'). Sense 3: second person ('you'), extremely rare and context-dependent. Both are obsolete in modern Japanese.
古語では「我が党」を一人称として使うことがあった。
In classical language, 'wagatō' was sometimes used as a first-person pronoun.
Compound of 我が (wa ga, 'my/our', classical possessive) + 党 (tō, 'party'). The archaic pronoun senses derive from classical usage where 我が党 could refer to 'one's own side' and by extension 'I' or 'you' in certain contexts.
