The quality or state of being dilatable; the capacity to be stretched or expanded.
From dilatable + -ness (noun suffix). A double suffix formation: dilate + -able + -ness, creating an abstract noun describing the quality of expandability. More philosophical than dilatabiltiy.
While 'dilatability' sounds technical and scientific, 'dilatableness' has an older, more philosophical feel—it's the kind of word you'd find in 18th-century philosophical essays about the nature of matter.
