birefringence singular

Morphology

birefringence = birefringent (semi-transparent) = bi + refring + ence

The noun is formed regularly from the adjective 'birefringent' by the nominalizing suffix '-ence'.

Etymology

The word birefringence comes from bi- meaning 'two' and a root like refract, as in 'refraction', meaning 'to bend' or 'break' light. So birefringence describes a material that literally makes one beam of light split into two rays, which is why the word means that property today.
