murine

The word 'murine' traces its lineage directly to Latin, built from the noun mūs (mouse) and the adjectival suffix -īnus. The Latin mūs itself descends from the Proto-Indo-European root mūs-, which also gave rise to words for mouse in many other languages, including Ancient Greek mûs and Sanskrit mūṣ-. The suffix -īnus is a productive Latin form for creating adjectives denoting characteristics or relations. Thus, the literal construction "of or pertaining to a mouse" evolved into the modern, specialized zoological and medical term used to describe rodents of the family Muridae or anything resembling them.

Structure: mur (mouse) + ine (relating to) - mur: From Latin mūs (genitive mūris), meaning "mouse." In this word, it appears as the stem "mur-". - ine: A suffix of Latin origin (-īnus), used to form adjectives meaning "of or pertaining to," "of the nature of," or "like."
