The word playwright is in the same etymological family as that of a shipwright, a cartwright, a wheelwright. The words shipwright, cartwright, wheelwright are descriptive: they summon up a craftsperson making a useful object – a ship, a cart, a wheel. A playwright is the maker of a script for the stage, a useful text. The second half of the word play-wright, then, emphasizes the craft aspect of writing for the stage.
