Colonette

A colonette is a small slender column,[1] usually decorative, which supports a beam or lintel. Colonettes have been used as a feature of furnishings such as a dressing table and case clock.[2][3] According to Webster's Dictionary, they are typically found in "a group in a parapet, balustrade, or cluster pier".[4] The term columnette has also been used to refer to thin columns.[5]

The -ette suffix, from French language, is a diminutive.
