Realisability

Part of speech: noun

Definitions

1. the attribute of being capable of implementation or fulfillment the possibility for a concept or plan to transition into reality the measure of how effectively an idea can be brought to fruition
2. The quality of being capable of successful execution or actualization
3. The likelihood that a project or idea can be effectively realized or carried out

Etymology: "Realisability" is simply "realise" with the suffix "-ability" attached. "Realise" comes from "real" plus the verb-forming ending "-ise", so the word is built from the same root that gives "real" its sense of actual or existing. The suffix "-ability" turns a verb into a noun meaning the quality or capacity of being able to be done, so "realisability" names the capacity of something to be carried into effect or made actual. The word's meaning follows that logic: a plan, dream or design with high realisability is one that can plausibly become real. Because "realise" in English also means to grasp something mentally, the noun can carry a sense of what is achievable in practice rather than merely imagined. The word is a plain, transparent formation, so its history is best understood by looking at its two parts separately.
