blanca f. (Noun) "copper coin"
15th cent. Originally a name of silver coins minted during the reign King Juan II of Castile. Blanca referred to the silver content in the coin after whitening, while a coin without the treatment was nicknamed negra or prieta. As the silver content in the coin declined over time, the connection between blanca and the coin's luster diminished. Eventually blanca came to mean any copper or silver coin from the Medieval period. For a continuing etymology of blanca, see blanco.
For the origin of the surnames Blanca, Blancas, and Lablanca, the word was originally applied as a nickname to blond-headed women.
blanco (Adjective) "white"
12th cent. From Vulgar Latin *blancus 'id.' From a West Germanic source meaning "white" (compare Old High German blanc "shining," "white"). Ultimately from Proto-Germanic *blanka- "colorless."

bodega f. (Noun) "winery;" "granary;" "cellar;" "pantry"
11th cent. From Vulgar Latin *potheca "storeroom," "pantry" from Latin apotheca 'id.' Loss of the initial vowel a- in Vulgar Latin was due to interpreting illa apotheca "the pantry" as illa potheca (Roberts 2014). Latin apotheca was borrowed from Ancient Greek ἀποθήκη (apothéke) "storehouse," composed of ἀπό (apó) "far from" (see ab-) and τῐθέναι (tithénai) "to put," "to establish." From Proto-Indo-European *dhi-dheh1-mi "I put," reduplication of the root *dheh1- "to put" (see dar).

Old High German wag "waves," Gothic wegs "storm," "raging waves"). From Proto-Germanic *wēgō "dislocation." From Proto-Indo-European *u̯eǵh- "to move."
