Don't say "had rather," "had better," for "would rather," "would
better."
Don't speak of articles of diet as "healthy," but as "healthful" or
"wholesome."
Don't say "fix my gown," "fix this room," but "arrange my gown," "the
room." The best authorities rarely use fix, except to indicate
stability or permanence. You don't fix the house, you repair it.
