Change the word "Continue Reading"

add this function into functions.php of your child theme, and edit the text there:

/**
 * Returns a "Continue Reading" link for excerpts
 */
function twentyeleven_continue_reading_link() {
	return ' <a href="'. esc_url( get_permalink() ) . '">' . __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'twentyeleven' ) . '</a>';
}
// twentyeleven_continue_reading_link

hmm. it doesn’t work. This is my code

<?php

/** Tell WordPress to run post_theme_setup()
* when the 'after_setup_theme' hook is run.
*/

add_action( 'after_setup_theme', 'post_theme_setup' );

if ( !function_exists( 'post_theme_setup' ));
function post_theme_setup(){
/**
 * Returns a "Continue Reading" link for excerpts
 */
function twentyeleven_continue_reading_link() {
	return ' <a href="'. esc_url( get_permalink() ) . '">' . __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'twentyeleven' ) . '</a>';
}

}
endif;

this should be your code:

/* Returns a different "Continue Reading" link for excerpts in child theme */
function twentyeleven_continue_reading_link() {
	return ' <a href="'. esc_url( get_permalink() ) . '">' . __( 'Another Word <span class="meta-nav">&rarr;</span>', 'twentyeleven' ) . '</a>';
}

or alternative:

/**
 * Returns a different "Continue Reading" link for excerpts in the child theme
 */
function twentyeleven_continue_reading_link() {
	return ' <a href="'. esc_url( get_permalink() ) . '">' . 'Another Word <span class="meta-nav">&rarr;</span>' . '</a>';
}

Perfect! it works now. Thank you very much
