How can I set the 'Language' field under  'Communication preferences' tab as a required field?

Alternatively, how can I set a default value for it?
(I don't want that default value to mess with the whole of the CiviCRM environment, though, as in Administrater|Localization|Languages)

Thnx in advance!

Joanne's approach is a good one.  If you need to keep the existing entry forms, but just need to make a field required, you need a little bit of custom code.  The best way to do this is by making an extension - use "hook_civicrm_buildForm".  I made the "Contribution Page" field required when entering a contribution from the back end with this code:

function backenddonations_civicrm_buildForm( $formName, &$form) {
  if($formName == CRM_Contribute_Form_Contribution) {
    //make Contribution Page ID required.
    //but this hook gets called for all the subsections of this page, so only call it when applicable.
    if(array_key_exists('contribution_page_id',$form->_elementIndex)) {
      $form->addRule('contribution_page_id', ts('Contribution Page name is required.'), 'required');
    }
  }
}
