Tolerability comes from tolerable + -ity, ultimately from Latin tolerāre ('to bear, endure'). The historical chain includes Latin tolerāre and Proto-Indo-European *telh₂-. The quoted older sense, "to bear, endure," supplies the immediate semantic anchor for tolerability. The formation is best read as suffixal and borrowed: the word tolerability carries its older form-history into a compact English lexical shape. In present English it is used as a noun, "the quality of being bearable or endurable". Related English forms include tolerable, tolerate, toleration, and tolerance. The result is a noun whose etymology preserves both the older form and the later English specialization.
