getteredadj.

Brit.

/ˈɡɛtəd/, U.S.

/ˈɡɛdərd/

Origin: Formed within English, by derivation. Etymons: getter n., -ed suffix²; getter v., -ed suffix¹.

Etymology: < getter n. + -ed suffix². In later use probably partly also < getter v. + -ed suffix¹.

1. Of a device or material: supplied or treated with a getter (getter n. 2c); containing a gettering agent.

1925 F. H. Newman Production & Measurem. Low Pressure vii. 133 In the ‘gettered’ lamp a solution of red phosphorus in alcohol was painted on the leads below the filament.

2. Of an impurity: removed by a getter; subjected to gettering.
