92. There is a subtle distinction between the idiom "so x as to y" and “x is enough to y.” "so x as to y" is used to indicate that characteristic x is so extreme in the particular case that y results. In contrast, the idiom "x is enough to y" is used when x is the criteria by which an ability to achieve y is measured. Thus, if a sentence stated that "a category 5 storm has wind speeds high enough to blow away small buildings," this would convey a different meaning: that wind speeds are the criteria by which one measures the ability to blow away small houses.
