"One example is when you're speaking a second, third... whichever language. If it's something you've learnt after your first language, which most people have done, then your vocabulary is less developed and whilst you may be fluent in basic conversational skills there are occassions when you can back yourself into a corner by trying to carry on a conversation like you would normally and then realizing that you don't actually know the particular word you were planning on using and have to think for a moment to replace the word."


"I think it's something we learn along with our conversational skills. It's developed as part of our vocabulary because as a child, we're mimicking the adult conversations we hear."
