French has a lot of lenition, for example, where the endings of words blend with the start of the following words. Such abbreviation in speech is common in African-American Vernacular, which makes the language sound more informal and "street." However, vulgar languages have a way of eventually becoming mainstream. For example, Shakespearean English was the English of commoners. Likewise, French is now considered an exporter of classy European culture, with the Louvre being the most famous museum in the world. The lower classes typically focus on creativity as a way to grab the attention of the upper classes. Likewise, it could be that early, lower-class French was the "street" language of the bohemian artists and musicians, who eventually created the bulwark of future French culture.
