This article discusses why children call their parents 'Mom' and 'Dad', and why not other names. It talks about how the role sounds play, and the role that cultural rules play in why most people refer their parents in this way.

This article talks about why we say 'Ok'. It discusses how long we have been using it, and the possible suspected origin of the usage of the word.

This article is about how experts believe they have found the 'first compelling evidence' for conformity to linguistic laws in non-primate species. A new study from the University of Torino has found the animals obey some of the same rules of linguistics as humans. The animals follow two main laws - that more frequently used words are briefer (Zipf's law of brevity), and longer words are composed of extra but briefer syllables (the Menzerath-Altmann law). Scientists say this is the first instance of these laws observed outside primates, suggesting an ecological pressure of brevity and efficiency in animal vocalisations.

This article is about how a child's first language can include more than just words. According to UNESCO, "Mother tongue or mother language refers to a child's first language, the language learned in the home from older family members." A child's language should be allowed and encouraged to be multilingual if their culture has a different language. There is more to a child's first language than just words because it also includes cultural and ancestral history that should and can be passed on to future generations. But since in some households parents don't encourage their children to learn their cultural language many children are losing out on this.
