Hey there @roberthedlund,
You can show the first two words of the product title in bold letters but that will require adding both HTML tags and CSS codes to the theme.
You can see how to bold the words here: https://stackoverflow.com/questions/9058425/how-to-bold-words-within-a-paragraph-in-html-css
I strongly recommend you create a child theme when doing customizations like this to make it easier to update your theme in the future and keep track of the changes you have made. Please see our tutorial on best practices when creating a child theme here: https://www.woocommerce.com/tutorials/customizing-a-child-theme/
An alternative could be to simply bold the entire title block using the code below:
.wc-block-grid__products .wc-block-grid__product .wc-block-grid__product-title {
font-weight: bold;
}
