Common Mistakes

Using curve as if it always means a baseball pitch. The most common meanings are the verb 'bend' and the noun 'a curved line or shape'.
Confusing curve with straight line; they are opposites in the shape sense.
Writing 'curve ball' as one word in normal usage; it is usually 'curveball' or 'curve ball' depending on style, but the supplied source uses 'curve ball'.
