When we get stuck in conversation and we're having trouble accessing a word we want to use, it can be helpful to talk around the word.
For example, if I'm talking about a pencil, but having trouble finding, accessing and saying the word pencil, I might say:
“It's something we can write with” or “I use it at school to write my papers.”
Just saying this out loud might help you access and say the word “pencil.”
