rime

The noun is derived from Middle English rim, rime, rym, ryme (“hoar frost; rime”), from Old English hrīm (“frost”), from Proto-West Germanic hrīm (“rime; hoar frost”), from Proto-Germanic hrīmą (North Germanic), hrīmaz, hrīmô (“rime; hoar frost”), probably from Proto-Indo-European *krey- (“to graze, touch; to streak”). The verb is derived from the noun. (The Old English equivalent, which did not survive into modern English, was behrīman.)

The noun is derived from Late Middle English rim (“cleft, crack, fissure”), from Latin rīma (“chink, cleft, crack, fissure”), ultimately from Proto-Indo-European *(H)reyH- (“to cut; to tear”). Doublet of rima. The verb is derived from Latin rīmārī, the present active infinitive of rīmor (“to explore; to probe; to search”), from rīma (see above) + -or.
