Plural of fluting; grooves or ridges carved lengthwise, especially on columns or decorative objects; also, the act of producing such grooves.
From 'flute' (to groove) plus '-ing' (forming nouns from verbs). The architectural term became common during the Renaissance as classical styles were revived.
Look at old buildings and you'll see flutings everywhere—architects used them partly for beauty but also for practical reasons: grooved columns actually resist wind stress better than smooth ones.
