Languages are not part of societies as rigid structures, and presenting unmodifiable corpora of vocabulary and grammar rules. Languagens, actually, may change, and they do so for many different reasons. This may occur diachronically, all along the time, or on a synchronic base, in one specific gap or era. This can seen, for instance, with a glance at the influence of the English language on tecnologial and digital vocabulary in the present days.

Some of the reasons that may cause a language to change may be:

1. New necessities for the speakers who, then, create new words for them.
2. The launching of new products produces new experiences, which produces new vocabularies.
3. The abandon of dictionaries on the profit of contacts between cultures produces a less proficient community of speakers.
