Pronunciation

Forms

grumo m (plural grumi)[1] A rare variant is grummo.[2]

Etymology

It is inherited from Latin grūmus (“heap of earth, mound”), from the accusative.[3][4][5][6][7] Zingarelli calls it a learned word,[8] but DEI shows that the Latin word lived on in the dialects, as Old Trevisan grun and Friulian grum with the old sense “heap”, and with the Italian sense in Piedmontese, Genoese and Alpine Venetian.[9] The same word is Catalan grum, Spanish grumo and Portuguese grumo.[4][10] The popular gromma goes back to the same Latin word.[4][11]

DELI calls the Latin word a rare technical word of unknown origin.[3] DEI took it as a probable Mediterranean relic.[9] De Vaan instead reconstructs Proto-Italic *grōmo-, from Proto-Indo-European *h₂ǵr-ōm-o-.[12] He connects it with gremium (“lap”) and with Proto-Slavic *gromada (“heap”), with a change of /ō/ to /ū/ before /m/ that he also sees in hūmānus.[12][1]

Earliest recorded meaning

The TLIO's first record is in the poems of Francesco di Vannozzo, 1374, in a figurative heap or mass.[7] DELI dates the sense “a small quantity of curdled liquid, especially blood” to Pietro Andrea Mattioli in 1563, whose grumi di sangue describe the resin called dragon's blood.[3][2]

Semantic evolution

Francesco Redi put grumo and grumoso into the Crusca dictionary with quotations he falsely attributed to the 14th century.[3] The blood clot remains the main sense: Berchet writes of i grumi del sangue on old halberds and Pascoli of blood left only arso, in grumi, dried into clots.[2]

The extended sense of a lump in a badly mixed paste is dated from 1884, with Giovanni Faldella's grummi of boot polish and D'Annunzio's grumi.[3][2] An old sense, the bud of a flower, is now obsolete,[8][13] and geology uses the word for small rounded grains in some sedimentary rocks.[5][14] Place names called Grumo come from the sense “hill”.[15]
