c. 1300 (mid-13c. in Anglo-Latin), "wreath of flowers," also "crown of gold or silver," from Old French garlande "garland," probably from a Frankish frequentative form of *weron "adorn, bedeck," from *wiara-, *weara- "wire" (on the notion of "ornament of refined gold," properly "of twisted gold wire"), from Proto-Germanic *wira-, *wera-, suffixed form of PIE root *wei- "to turn, twist." Compare Middle High German wieren "adorn, bedeck." The word is found in many forms in the Romanic language, such as Old Spanish guarlanda, French guirlande, Italian ghirlanda, Portuguese grinalda.
early 15c., "to make a garland;" 1590s, "to crown with a garland," from garland (n.). Related: Garlanded; garlanding.
