+# Isogram
+
+Determine if a word or phrase is an isogram.
+
+An isogram (also known as a "nonpattern word") is a word or phrase without a repeating letter.
+
+Examples of isograms:
+
+- lumberjacks
+- background
+- downstream
+
+The word *isograms*, however, is not an isogram, because the s repeats.
+
+## Source
