POLOS CAMIÑOS DA MOTIVACIÓN E DA XEOLINGÜÍSTICA: OS NOMES DA VÍA LÁCTEA

This article studies the names of our galaxy in the linguistic domain of Galician and Portuguese (spoken in Portugal and Brazil), based mainly on data extracted from the Galician and Portuguese word bank (Tesouro do léxico patrimonial galego e portugués). We analyse the data from the point of view of motivation, deeply rooted in the ancient beliefs with which human beings integrated this phenomenon into different cultures worldwide. This perspective is particularly relevant in the geographical scope of the Galician-Portuguese linguistic continuum, which extends on both sides of the Atlantic Ocean and overlaps with other languages and cultures from very different families. The data is also analysed from a geolinguistic point of view, by showing the relationship between the distance from the original cultural centre, the continuity or loss of motivation, and the changes in the adopted linguistic forms, not overlooking the possibilities of acquisition of new motivations through hybridisation during the territorial expansion.Estudamos as denominacións da nosa galaxia no dominio lingüístico do galego e do portugués en Portugal e no Brasil, con base principal nos datos do Tesouro do léxico patrimonial galego e portugués (TLPGP). Analizámolas desde o punto de vista da motivación, moi arraigada en crenzas ancestrais con que a humanidade integrou ese fenómeno celeste en diferentes culturas ao longo de todo o mundo; esta perspectiva ten especial importancia no ámbito territorial do bloque lingüístico galego-portugués, ao se estender en áreas transoceánicas e superpoñerse a outras linguas e culturas. Analizámolas tamén desde o punto de vista xeolingüístico, mostrando a relación entre o afastamento do núcleo cultural orixinario, a vixencia ou perda da motivación e a mudanza na forma lingüística adoptada, sen esquecermos as posibilidades de novas motivacións adquiridas por hibridación nesa expansión territorial
