Remove words from T9 dictionary? | Phone/Device Issues and Features | Consumer forum

I have the Nokia 1661, and I use it for texting a lot. Of course, the predictive text dictionary doesn't include a few words, so I add them myself.

Problem is, I want to remove some of the words now (some due to mis-spellings, others because they appear before a more commonly used word). Does anyone know how to do this?

Your assistance is greatly appreciated.
