What is the term for the additional strokes that enhance letterforms in decorative calligraphy?

The correct term for the additional strokes that enhance letterforms in decorative calligraphy is "flourishes." Flourishes are ornamental strokes that are often applied to the ends of letters, adding elegance, movement, and a sense of artistic flair to the overall design. These decorative elements are typically created with a sweeping motion, emphasizing the beauty and individuality of each letter and the piece as a whole. Flourishes serve to draw attention and enhance the visual impact of calligraphic work, making them a crucial component in many styles of decorative lettering.

In contrast, serifs refer to the small lines or decorative features found at the ends of the strokes of a letter. Stems are the main vertical or diagonal strokes of a letter, and crossbars are horizontal strokes that connect two vertical elements in certain letters. While these components contribute to the structure of typefaces and letterforms, they do not embody the additional artistic embellishments that flourishes represent.
