The word yet keeps a statement true while leaving a window open inside it.

One syllable holds a statement open. It concedes the present fact and refuses to close the future, which turns a verdict into a status report, and the difference in how it feels to live under is considerable. Not good at this and not good at this yet describe the same afternoon.

Put it into your own sentences and into what you say to others, particularly children and anyone learning something. And check where you have been using permanent language about a temporary state. The word costs nothing and it keeps the door on its hinges.
