What exactly does いな mean in Japanese?


I know it seems like いいな means "that's good" but in anime like Akagi and
Kaiji, the narrator says いな and the subtitles translate it as "that's wrong".
Is いな some kind of old phrase for "that's wrong"? What does it mean?




いな is an archaic form of 'no' (sometimes written with kanji as 否). You can
still hear it in modern Japanese in a few phrases, like ～か否か ('whether or not
～').

いいな is, of course, いい+な, i.e. 'that's good'.
