any of a number of scratches or parallel grooves on the surface of a rock, resulting from the action of moving ice, as of a glacier
4. Biology
any of the alternating light and dark crossbands that are visible in certain muscle fibers, esp. of voluntary muscles, and are produced by the distribution of contractile proteins
Word origin
[1840–50; striate + -ion]This word is first recorded in the period 1840–50. Other words that entered Englishat around the same time include: colloid, dope, layout, pylon, sensationalism-ion is a suffix, appearing in words of Latin origin, denoting action or condition, usedin Latin and in English to form nouns from stems of Latin adjectives (communion; union), verbs (legion; opinion), and esp. past participles (allusion; creation; fusion; notion; torsion)
