This essay deals with the lexical renovation begun by the Spanish-American modernist poets at the edge of the 19th and 20th century. It intends to classify their attempts into two categories, depending on whether the lexical elements were "tied" to certain tradition or the poetic matter itself, or if they were rather "untied", i.e. newly conceived or used with a distance in regard to the poetic matter.
It sees the modernity of their lexical renovation not only in the usage of new words, but especially in the fact the modernists wittily combine old, rescued words from the past with the modern ones, such as words denominating new technical inventions.
