Ses-qui-quad-rate
/ˌsɛskwɪˈkwɒdreɪt/
The sesquiquadrate, also known as the sesquisquare, is an astrological aspect formed when two planets or points are separated by an arc of one hundred and thirty-five degrees.
This aspect is considered a minor hard aspect and is mathematically related to the semi-square and the square. It represents a persistent state of tension or irritation that often manifests as external obstacles requiring patient effort to overcome. Unlike the immediate pressure of a square, the sesquiquadrate suggests a situation that needs ongoing refinement and adjustment over time. In a birth chart, it points to areas where an individual may experience friction between their needs and the surrounding environment.
