Just to slightly tease Celu so I can see her make that face I will only write the thing in Undercommon. In truth, I do know she doesn’t like when I use it because she doesn’t understand what is being said. So below is a list of common phrases, she should be able to pick the language up quite quickly since undercommon has its roots in elven. It even uses some of the letters.
((There is a list of letters written that correspond to Undercommon alphabet. Along with a list of key phrases that are written correctly and phonetic spelling of those words and sayings. Aniks has also given Celu the grammatical rules to undercommon but they're incredibly similar to Elven.))
