We can easily add an excerpt on any WordPress post or post-types. But there is no built-in option to add an excerpt on WordPress pages.
But we can enable the option to add excerpts on WordPress pages by using the below function.
We need to add the below function on functions.php file active theme.
//write this on function.php
add_action('init', 'my_custom_init');
function my_custom_init() {
add_post_type_support( 'page', 'excerpt' );
}
