Apple Watch has a built in response of "一个字。非常棒！". Is this correct? When you respond to a text message on Apple Watch, there are a number of autoreply options. One of them:


  一个字。非常棒！


I translate this to English as "One word. Excellent! ". This makes a lot of sense in this translation. However, can the entire phrase "非常棒" (excellent) be considered one 字 (word)? Or is a 字 strictly considered a single character?
No it's not correct. "非常棒" are definitely three 字s. So the proper form should be


  一个字。棒！


or


  三个字。非常棒！


According to the context this kind of wording might be used on purpose for joking; you might not need to take them seriously.
