þríhyrndra

þríhyrndra is the genitive plural form of the Old Norse word "þríhyrndr," meaning "three-cornered" or "triangular." In Old Norse literature and historical contexts, this term would typically be used to describe objects or entities possessing three distinct angles or corners. It could refer to geographical features, such as a triangular piece of land, or to manufactured items. For example, a shield might be described as þríhyrndra if it had a triangular shape, or a building's foundation could be characterized as such. The adjective's grammatical form, genitive plural, indicates possession or relation to multiple three-cornered things. Therefore, any phrase using "þríhyrndra" would imply a connection to or description of more than one triangular entity. Its usage is primarily found in older texts and would require knowledge of Old Norse grammar and vocabulary for full comprehension. The root word "þrír" signifies "three," and "hygndr" relates to "corner" or "angle."
