textraneous

a textbook you're supposed to buy for a class but never end up using

etymology: textbook + extraneous = textraneous

I'm not buying any textbooks for this class until we're a few weeks into the semester. I have a feeling we're not going to use all of them and I'm not throwing away money on textraneous books

textraneous

text message that is unnecessary, especially if something like thanks would be implied

Man, I texted Renee to pick up some milk at the store so when I said thanks she texted back ur welcome - totally textraneous and a waste of my messages!
