Indubitably

The sentence that my mom (hi mom!) had me practice was a simple but effective way to get me to enunciate clearly. What they're supposed to be trying to say is...

Indubitably, that is specifically, though not particularly a necessity. 

I said this when I was.. what was it, 10 years old? I never forgot it, and trying to teach it to a 14 and 13 year old seems impossible.
