From <a href="http:&#x2F;&#x2F;www.lua.org&#x2F;about.html" rel="nofollow">http:&#x2F;&#x2F;www.lua.org&#x2F;about.html</a>:<p>&gt; &quot;Lua&quot; (pronounced LOO-ah) means &quot;Moon&quot; in Portuguese. As such, it is neither an acronym nor an abbreviation, but a noun. More specifically, &quot;Lua&quot; is a name, the name of the Earth&#x27;s moon and the name of the language. Like most names, it should be written in lower case with an initial capital, that is, &quot;Lua&quot;. Please do not write it as &quot;LUA&quot;, which is both ugly and confusing, because then it becomes an acronym with different meanings for different people. So, please, write &quot;Lua&quot; right!
