In chronic laryngitis the normal columnar cells undergo dysplasia, which is when they transform into squamous epithelium to adapt to the chronic irritation.
This causes the epithelium of the lower esophagus to constantly renew, and when it's replaced by columnar epithelium, that's called Barrett's esophagus.
Now the walls of the conducting bronchioles are similarly lined by ciliated columnar cells and mucus secreting goblet cells, as well as a new cell type called club cells.
