crude (or poorly put together, esp. with respect to a writing or speech) adj.: incondite

Suddenly I’m tired, despite the java fix, and resigned to the fact that come Monday, I’ll have about enough free time — between diaper origami and learning the baby language of the day and getting the turkey loaf done before my wife comes home — to write an incondite self-pitying limerick: “There was an old pop in Seattle/Who was stuck between bottle and rattle.” (R. W. Lucky, What I Want to Be After My Child Grows Up, The Seattle Times, 03/27/1994, p. L5.)

This word, when used in the above sense, can also be a synonym for coarse, unpolished or unrefined.
