Name these common words that end with "-stly", with some exceptions. There are several prefix/compound words in this one, so to make your life easier, they are tan instead of light blue. This one seemed pretty tough when I tested it!
Words under 0.000003% usage on Google Ngram are omitted.
Common words (over 0.00001%) that add a prefix to or form a compound word with a word already on the quiz are shown in tan.
For instance, "unwell" and "inkwell" would be tan for an Ends in "-well" quiz.
