// RETRIVE TERM SLUG ( for single.php or template-part )

$terms = get_the_terms( $post->ID, 'your-taxonomy' );

Example 2: wordpress get terms by taxonomy

You need to pass an additional argument to get_terms(). The default is to hide
"empty" terms-- terms which are assigned to no posts.

$terms = get_terms([
    'taxonomy' => $taxonomy,
    'hide_empty' => false,
]);
