How did Visigothic influence Spanish and Portuguese vocabulary?

The Visigoths, who occupied the Iberian Peninsula, were highly Romanized and had largely abandoned their native Germanic tongue by the 7th century CE. Because of this, their linguistic impact on Spanish and Portuguese was less extensive than that of other superstratum languages in other regions.1

While borrowings from Visigothic are less frequent, they remain significant. Several terms that entered the language during this period are common to both Spanish and Portuguese, such as estaca (stake) and brotar (to bud). These contributions represent a modest but enduring layer of the vocabulary in these Romance languages.1
