odder

The word 'odder' is the comparative form of the adjective 'odd'. The root 'odd' entered English from Old Norse 'oddi', which originally meant a triangle or the point of a weapon, and by extension, an odd number (as a triangle has three points). This sense of being unpaired or left over evolved into the broader meaning of something unusual or irregular. The suffix '-er' is a native Germanic comparative marker, directly added to the base adjective to create a form meaning 'more odd', following a standard and productive pattern in English morphology.
