שְׁרִיר (shrir) — muscle

Etymology

The Greek word mys (mouse) was used in antiquity for both the animal and the muscle, based on a perceived visual resemblance — particularly in the shape of the bicep. When Greek medical texts were translated into Latin, mys became musculus ("little mouse"), which gave rise to French muscle, English muscle, and German Muskel. A parallel translation chain ran through Syriac, where mys became okbara (mouse), and thence into Arabic as ʿaḍala, originally meaning "rat" in medieval Arabic but now simply meaning "muscle."

Medieval Jewish physicians, working within the Arabic medical tradition, used the Hebrew-Aramaic form ʿatsal for muscle — as seen in Zerachiah ben Shealtiel's Hebrew translation of Maimonides' Fusul Musa, which states: "The ʿatsal is an instrument for movement alone." When the Haskalah brought European scientific literature to Hebrew readers, early translators initially calqued the German Muskel directly as ʿakhbar (mouse). Baruch Linda's 1788 Reshit Limudim explains: "The ʿakhbarim (muscles) is a collective name for a piece of flesh made of a net of thin fibers and veins, shaped like a mouse."

The pivotal shift came in 1812 with Wilhelm Gesenius's lexicon of Biblical Hebrew, in which he identified the rare Biblical word sharir — appearing only once, in Job 40:16 describing the mythological beast Behemoth — as meaning Muskel rather than the previously assumed "navel." Gesenius likely drew on the Arabic cognate ʿaḍala, whose root ʿaḍ-l means "strong" — exactly the meaning of the Hebrew root shin-resh-resh underlying sharir. The Gesenius lexicon became the definitive authority for Biblical Hebrew, and Haskalah scholars followed his lead: Moses Studentskey used sharir in 1853 (after initially using ʿakhbar in 1843), Joshua Steinberg in 1860, and Mendele Moykher Sforim in 1861.

The word entered the revived spoken Hebrew of the 20th century in the form שְׁרִיר (shrir, with a shva under the shin) rather than the Biblical שָׁרִיר (sharir, with a kamatz). This is because the word was almost always encountered in its plural form shririm or in construct state shrir ha-..., where the vowel shift is regular. Since nearly all speakers learned the word in those forms, they generalized the shva-pronunciation to the singular as well. By the time dictionaries and the Academy of the Hebrew Language weighed in, the pronunciation shrir was already universal and was eventually codified as the standard form.
