adaptness
/əˈdap(t)nəs/noun
= adaptedness. In later use also (frequently with at): = adeptness.
- In later use equivalent to adeptness perhaps only a typographical error..
Origin
Mid 17th century; earliest use found in John Gaule (1603/4–1687), Church of England clergyman and author. Apparently from adapt + -ness. Compare slightly later adapt and discussion at that entry.
