Triquetra is a three-cornered, knot-like symbol used in various contexts (notably Celtic and neopagan imagery) to represent unity and the interconnectedness of three elements. In broader usage it designates a triple-loop motif, often with continuous, interlaced lines. The term also appears in heraldry and literature, and foundationally it refers to a triadic, interwoven design rather than to any single letter or word meaning.
