This is the 1417th most frequent Korean word.
의원도
"의원도" does not have a standalone meaning in Korean and may be a typo or incomplete phrase.
In this sentence, "의원도" emphasizes that the council member, in addition to others, participated in the meeting.
의원도 회의에 참석했습니다.
The council member also attended the meeting.
Here, "의원도" suggests the implication that even someone who isn't a council member contributed their opinion, introducing a contrast.
그녀는 의원도 아닌데 의견을 냈다.
She gave her opinion even though she is not a council member.
In this case, "의원도" refers specifically to the particular council member agreeing in addition to others who agreed.
