In heraldry, an ordinary which is cotised has a narrow line, or cotise, running parallel to its edges. Cotising an ordinary is considered as adding a secondary charge. The cotise is typically depicted as 1/4 of the width of the ordinary.
The cotises for some ordinaries have special names. The cotises of a pale are called endorses, and so instead of being blazoned a pale cotised, it is instead a pale endorsed. The cotises for a chevron can also be called couple-closes.
