ASCII 121 holds lowercase y. In YAML ("YAML Ain't Markup Language"), certain bare strings like yes, no, true, false, on, off are automatically converted to booleans, a design choice that has caused data corruption bugs (the "Norway problem" where the country code NO becomes boolean false). In CSS, y appears in the translateY() and scaleY() transform functions. In algebra, y is the conventional dependent variable, paired with x on the horizontal axis.
