stabilizability
|sta-bi-li-za-bi-li-ty|
/stəˌbɪlɪzəˈbɪlɪti/
able to be made stable
Etymology
'stabilizability' originates from English constructions built on the verb 'stabilize' and the suffix '-ability'. 'Stabilize' itself comes from the adjective 'stable' (from Latin 'stabilis'), with the verbalizing suffix '-ize' (from Greek/Latin formation), and '-ability' (from Latin '-abilitas' via Old French) forming the noun meaning 'the quality of being able to be stabilized'.
'stable' comes from Latin 'stabilis' meaning 'firm, steady'; this produced the verb-forming pattern (English) 'stabilize' (to make stable), and modern English formed the abstract noun 'stabilizability' by adding '-ability' to indicate the capacity to be stabilized.
Initially related words meant 'able to stand or be steady' (from Latin 'stabilis'); over time the formation with '-ize' and '-ability' produced the modern technical and general sense 'the capacity to be made stable'.
