I'm along the way of adding some lines of code to alter the word what instantly once the language is transformed within the language selection module. Among my component in Joomla, it does not respect the word what altering through language selection.

it's already the word what.ini file is incorporated in the language directory is akin to this language. However the language isn't transformed. Can there be any special joomla code to really make it dynamic?

You need to output text in Joomla such as this:

echo JText::_("HELLO");

You'll also find to produce an ini file using the language code and also the title from the component/model. E.g.: en-GB.mod_modulename.ini. Within this file you are able to define the translation for that string, like:

HELLO=Hola

When switching the word what, the lines where JText can be used, displays the right language.
