En ga nai (縁がない) is a phrase meaning "to have no connection to/no opportunity to", but I`m still not sure of all of its implications, or uses. Have you heard this phrase before?
縁・えん seems a bit similar to 運・うん (as in 運命・うんめい・fate) , or 関係・かんけい・relationship, for example:
彼と縁がない・かれとえんがない `I don`t have any connection to him.`
But I think that the phrase can be read as more than just `connection`, and perhaps translated as something like, `We don`t see eye to eye`, `We aren`t meant to be`, etc.
ロシアに行くことと縁がない・ろしあにいくえんがない I don`t have the opportunity to go to Russia. But perhaps there is also an implication of, `I`ll probably never have the opportunity / It isn`t in my cards (It`s not my fate) to go to Russia`?
In an actual article (from the Asahi Shinbun, 非難し合うより共闘しよう、ドリュー・ギルピン・ファウスト）, a line using this phrase shows up...
`Girls who until this had no connection to either myself or Harvard were overjoyed, believing that for themselves (as well) `a large door had opened in the world`.`
