Yes, that looks like something I am looking for although not sure if it is a best practice. Anyways, it looks like I need something similar to <time.inline> into which I can shove stuff like {{ .Params.descriptiopn }}. Is there something built-in? Or do I have to write it myself? You see the entire section _ Inline shortcodes_ is just a few words
While your experimenting, please notice: An arbitrary frontmatter parameter is accessible under .Params.arbitrary.
But the description parameter you chose in your example belongs to Hugo’s built-in set. It’s stored in .Description (as usual with an uppercase initial for built-in parameters).
