flustra

== Latin == === Alternative forms === flū̆strum (Medieval Latin) === Etymology === Seemingly from fluō (“to flow”) +‎ -trum. The -s- has been explained either as an analogically transferred consonant from words that originally had a root-final dental (e.g. rāstrum, rōstrum), or as a remnant of an original s-stem neuter noun suffix from *-os (with a phonetic development like *flov-os-tra > *floustra > flūstra; compare *re-vorsos > *rovorsos > *roursus > rūrsus); compare mōnstrum, lustrum and lūstrum. === Noun === flū̆stra n pl (genitive flū̆strōrum); second declension (pre-classical, post-classical) calm at sea, the quiet state of the sea Synonym: malacia ==== Declension ==== Second-declension noun (neuter), plural only. === References === === Further reading === "flustra", in Charles du Fresne du Cange, Glossarium Mediæ et Infimæ Latinitatis (augmented edition with additions by D.
