IPA: //sæˈfreɪnɪn//
KK: /sæfˈreɪnɪn/
A type of dye used in biology to color cells and tissues for examination under a microscope.
The scientist used safranin to stain the plant cells for better visibility during the experiment.
Safranin is derived from the word 'saffron' (from Arabic 'za'farān', meaning the flower of the saffron crocus), which refers to the dye obtained from the saffron plant. The suffix '-in' is commonly used in chemistry to denote substances, particularly dyes. Thus, 'safranin' refers to a dye derived from saffron.
Think of 'saffron' as the source of this dye, and remember that 'safranin' is a substance related to that beautiful flower.
