Change the english word

Hello,

I would like to change this word please : http://prntscr.com/jqzsv7

Could you help me please ?

Try this way:
- Open the file:
- Look for this line of code:

<a href="<?php echo $extra_link; ?>" title="More">More<i class="fa fa-arrow-right"></i></a>

change it to:

<a href="<?php echo $extra_link; ?>" title="More"><?php echo JText::_('MORE_VIDEO'); ?><i class="fa fa-arrow-right"></i></a>

Then go to back-end > Extensions > Languages > Override > add the translation for above language constant: MORE_VIDEO: http://prntscr.com/jr0lgp
