gum

An English word 'gum' can refer to sticky substance people chew or to a type of tree.

You might know that some people put something in their mouth and chew on it throughout the day. This thing they chew is called gum, usually sweet-tasting and often flavored with mint or fruit. People like to have a piece of gum when they're out and about, at work or school, to freshen their breath and make their mouths feel clean. Some people also use special kinds of gum to help with bad breath, dry mouth or even teeth whitening.
