Change Font of Single Word in Blog Post

I need to be able to change the font of single words inside paragraphs of Blog Posts. I have seen a lot of videos etc. that talk about modifying rich text, but this isn’t the answer.

The Blog Post editor only allows us to specify headings Bold, Italic and a couple of other style related items. This is not sufficient. How can I achieve the same result of WordPress where we use spans of fonts
