Genetics of Spanish vocabulary
The most essential part of the Spanish vocabulary is derived from Vulgar Latin. Thousands of words from classical Latin were included in the Spanish vocabulary with the development of the literary language.
Some words were borrowed from the languages of the pro-Roman inhabitants of the Iberian peninsula (the Iberians and the Celtiberians). The invasion of the Visigoths early in the 5th century AD introduced a few Germanic words; those of them which were beginning with w- received a prothetic g-, e.g., Gmc. werra war -> Sp. guerra.
The Muslim conquest in the 8th century later brought in a large number of Arabic words, many of which are easily detected by their polysyllabic structure (e.g., berenjena aubergine) or by the prefixed Arabic article al- (e.g., alcalde mayor, alfil officer, almohada pillow etc.)
Under the influence, beginning in the 11th century, of French ecclesiastics and pilgrims on their way to Santiago de Compostela in northwestern Spain, the Spanish vocabulary was appreciably augmented by words and phrases from French. During the 15th and 16th centuries an infusion of elements from the Italian occurred because of Aragonese domination in Italy and the great vogue of Italian poetry in Spain. Relations between Spain and its colonies and possessions have led to the introduction of terms from Native American languages and other sources, and scholarly activities have constantly increased the stock of borrowed words.
