Dear people writing in the TeX-based math notation here who want to include full-word variables: putting the word in raw leads to subtly bad formatting. If you just write “cake”, this gets typeset as though it were c times a times k times e, as in this example which admittedly doesn’t actually show how awkward it can get depending on the scale: cakebirthday. It’s more coherent if you put a \mathrm{} around each word to typeset it as a single upright word, like so: cakebirthday.
