Morphology
quadrature = quadrate (transparent) = quadrate + ure
The noun is derived by adding the nominalizing suffix '-ure' to 'quadrate', giving the process or result 'the act of making square'.
Etymology
The word quadrature comes from the Latin root quadr-, which means 'four', and from quadratus, which means 'square', so think of a shape with four equal sides. So quadrature is literally the idea of 'making a square', which is why in math it means finding a square with the same area as another shape.
