In linguistics, lexical similarity is a measure of the degree to which the word sets of two given languages are similar. A lexical similarity of 1 (or 100%) would mean a total overlap between vocabularies, whereas 0 means there are no common words. There are different ways to define the lexical similarity and the results vary accordingly.
This list contains Germanic elements of the English language which have a close corresponding Latinate form. The correspondence is semantic—in most cases these words are not cognates, but in some cases they are doublets, i.e., ultimately derived from the same root, generally Proto-Indo-European, as in cow and beef, both ultimately from PIE *gʷōus.
While the majority of lexical differences between Spanish and Portuguese come from the influence of the Arabic language on Spanish vocabulary, [1] [2] most of the similarities and cognate words in the two languages have their origin in Latin, [3] but several of these cognates differ, to a greater or lesser extent, in meaning.
For example, Latin habēre and German haben both mean 'to have' and are phonetically similar. However, the words evolved from different Proto-Indo-European (PIE) roots: haben , like English have , comes from PIE *kh₂pyé- 'to grasp', and has the Latin cognate capere 'to seize, grasp, capture'.
Semantic similarity is a metric defined over a set of documents or terms, where the idea of distance between items is based on the likeness of their meaning or semantic content [citation needed] as opposed to lexicographical similarity. These are mathematical tools used to estimate the strength of the semantic relationship between units of ...
In particular, words which appear in similar contexts are mapped to vectors which are nearby as measured by cosine similarity. This indicates the level of semantic similarity between the words, so for example the vectors for walk and ran are nearby, as are those for "but" and "however", and "Berlin" and "Germany".
Many of the words in the list are Latin cognates. Because Spanish is a Romance language (which means it evolved from Latin), many of its words are either inherited from Latin or derive from Latin words. Although English is a Germanic language, it, too, incorporates thousands of Latinate words that are related to words in Spanish. [3]
Comparative linguistics is a branch of historical linguistics that is concerned with comparing languages to establish their historical relatedness.. Genetic relatedness implies a common origin or proto-language and comparative linguistics aims to construct language families, to reconstruct proto-languages and specify the changes that have resulted in the documented languages.
