A horizontal or upward, sloping stroke that does not connect to a stroke or stem on one or both ends.

Definition: The arm of a letter is the horizontal stroke on some characters that does not connect to a stroke or stem at one or both ends. The top of the capital T and the horizontal strokes of the F and E are examples of arms. Additionally, the diagonal upward stroke on a K is its arm. Sometimes arm is used interchangeably with bar or crossbar or cross stroke.

Arm is often also used to describe the mostly horizontal top stroke of C, double-storey a, G, and other glyphs, to include the finial, terminal, spur, or other elements of the stroke.

Also Known As: crossbar, cross stroke
