Triquetra  ( pron.: / t r aɪ ˈ k w ɛ t r ə / ; Latin  tri-  "three" and  quetrus  "cornered") originally meant " triangle " and was used to refer to various three-cornered shapes. Nowadays, it has come to refer exclusively to a particular more complicated shape formed of three  vesicae piscis, sometimes with an added circle in or around it. This has been used as a religious symbol of things and persons that are threefold.
