  (ɔːˈstɪə(r))
  Forms: 4 auster, 7 -eer, 4– austere; also 4 austerene, awsterne (hausterne), 4–6 austerne, 6 austrun, astern.
  [a. OF. austere (14th c. in Littré), ad. L. austērus, a. Gr. αὐστηρός making the tongue dry and rough, hence, harsh, severe, f. αὔειν to dry. The adscititious -n, common in 14–16th c., is perhaps due to contact of form and sense with stern adj.; cf. quot. 1388 in sense 3. The appearance of the senses in Eng. does not correspond to the logical development in Gr.]
