Show text in a box when hovering over word

Question

I would like to show a definition of a word in a R markdown file when hovering over a word.

For a link it can be done like this: [I'm an inline-style link with title](https://www.google.com "Google's Homepage") Upon hovering over I'm an inline-style link with title the text Google's Homepage will pop up. However, I would like to do the same for a word and give the definition of the word in a box without the link.

Something like: [word]("Definition of word that pops up in a box upon hovering"). Is this possible?

One option is the tippy package.

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
library(tippy)
```

This is a 
```{r echo = FALSE}
tippy("word.", tooltip = "Definition of word that pops up in a box upon hovering")
```
I would like to know its definition.
