Use the display text from single option select in formula

When using a single option select the “internal” name is what’s used in a formula (ie, “This String” becomes “THIS_STRING”). Is there a way to use the display text instead of this internal name? In other words, in a formula I would like to have {Some Field}&”Is Short” output “This String Is Short” instead of “THIS_STRING Is Short”. I believe the function PROPER() would help but it appears that punctuation get’s left out of the internal name. Example… “Mr.” becomes “MR” as an internal name.
