Javascript - MathJax - Disable certain expressions -

is there anyway disable keywords in mathjax?

i have these:

´undefined´

,

´2m in cm´

on both "in" part replaced kind of ∈ value "undef∈ed" , "2m ∈ cm", how can prevent that?

try

`text{undefined}`

and

`text{2m in cm}`

for these. how should handling words in case, since `word` treated w times o times r times d, , rendered in math italic rather text font.
