avalanche: [18] Not surprisingly, avalanche originated in the Alps. The French dialect of Savoy, an area near the Italian border in the western Alps, had a term lavantse, apparently derived from a Vulgar Latin *labanca (whence Provençal lavanca). Through association with the verb avaler ‘descend’ (see DOWN), this underwent metathesis (transposition of l and v) to produce in the Romansh language of Switzerland avalantze, which was borrowed into French as avalanche.

avalanche (n.)youdaoicibaDictYouDict
1763, from French avalanche (17c.), from Romansch (Swiss) avalantze "descent," altered (by metathesis of -l- and -v-, probably influenced by Old French avaler "to descend, go down") from Savoy dialect lavantse, from Provençal lavanca "avalanche," perhaps from a pre-Latin Alpine language (the suffix -anca suggests Ligurian). As a verb, from 1872.
