X限り (かぎり),Y as “as far as X, Y”
With a different interpretation of 限り (かぎり)’s definition of “extent, limit, bound, etc.” it can also be used as a grammar pattern to mean “as far as X, Y.” This construction indicates the limit to which an action occurs. It is most commonly used with VERB words such as 知る (to know), 見る (to see), 理解する (to understand), to state one’s judgment upon something.
