Are these languages really similar?
In semantics, the lexical similarity is an evaluation of the degree to which the word sets of two different languages(given for testing) are similar. A lexical similarity of 1 (or 100%) would mean a total overlay in the middle of vocabularies, whereas 0 means there are no common words. Using such a method, an estimation was made regarding the lexical similarity of English was evaluated to have a lexical similarity of 57% with Spanish, 60% with German, and 27% with French. Lexical similarity is always used to evaluate the degree or estimation of genetic relationships between two languages. According to this relationship, the lexical similarity of two languages is higher than 85% usually indicates that those languages are likely to be related dialects.
The French and English languages are related in perception because French is a Romance(from the Indo-European family) language descended from Latin with German and English influences, while English(West-Germanic) is a Germanic language with Latin and French influences, and in the way, they share a portion of similarities, most notably the same alphabet structure and a number of true relations.
