NOTES

First I thought it means "to be at odds with someone" but now I think it means "to break away from someone". because if you leave your partner you "go" different ways. Dropping the prefix "tsu" leads to "gangen" which is MAYBE the preterite of "geyn". Following that, maybe it is "zikh tsugeyen" in present tense. Quoted from FA''S May 1973, p.6.
