In the sport of Australian rules football, each of the eighteen players in a team are assigned to a particular named position on the field of play. These positions describe both the player's main role and by implication their location on the ground. As the game has evolved, tactics and team formations have changed, and the names of the positions and the duties involved have evolved too.

Word sense
In linguistics, a word sense is one of the meanings of a word. For example a dictionary may have over 50 different meanings of the word play, each of these having a different meaning based on the context of the word usage in a sentence. For example: We went to see the play Romeo and Juliet at the theater. The children went out to play in the park. In each sentence we associate a different meaning of the word "play" based on hints the rest of the sentence gives us.
