Tutoring English, the coordinating conjunctions are important. The tutor brings up yet.
Yet is a coordinating conjunction that can add meaning. Consider the following two sentences:
The owner threw the ball far away, but his dog fetched it.
The owner threw the ball far away, yet his dog fetched it.
Perhaps the word yet can give a livelier sense sometimes.
