Ideally I would prefer

2) Or are you instead trying to remove only the specific word "Category:" or "Tag:" and leave visible the name of the category itself, like "Travel"?

For now I’ve added the code you mentioned and that’s half my problem solved, thank you so much Kathryn for taking the time to help me!

Thank you, webkong and Siobhan!
I set up the child theme and followed the notes above and from the link you sent (https://codex.ww.wp.xz.cn/Child_Themes), but I seem to have done something wrong because I caused my site to go down when I uploaded the child theme. I had named the child theme folder “canard-child”. I’m not sure what I’ve missed?
I also included the enqueuing for rtl.css – was I supposed to skip that?
Appreciate your help, as always. Thank you.

This is the style.css I used:

/*
Theme Name:   Canard Child
Theme URI:    http://www.theindiaedition.com/canard-child/
Description:  Canard child theme
Author:       DRD
Author URI:   http://www.theindiaedition.com
Template:     canard
Version:      1.0.0
Text Domain:  canard-child
*/

And this is my functions.php file:

<?php
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );

add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/rtl.css' );

if ( ! function_exists( 'the_archive_title' ) ) :
/**
