Guillem is a word that refers to a punctuation mark similar to an arrow or a chevron. It is also known as the angle bracket or the less than / greater than symbol. While guillem is the common term used in French and Catalan, other languages have different names for it. For instance, in Spanish, it is called "signo de mayor que/menor que," while in Portuguese, it is known as "símbolo de maior que/menor que." In English, this punctuation mark can be referred to as "angle brackets," "angle quotes," "chevrons," or "bracket arrows." Regardless of its name, guillem is mainly used to enclose certain sections of text and to indicate a quote, dialogue, or citation.
