President Obama drew criticism when he unveiled his campaign slogan: “Forward.”

The one word—plus the period—doesn’t move people to action in quite the same manner as his 2008 slogan “Yes we can.” Plus, it lends itself to parody, as many of his critics have tacked on additional commentary, such as: “Forward … off the cliff.”

Some grammar buffs, on the other hand, have a different problem with the slogan: It includes a period, even though “Forward” is not a sentence. So, grammatically, it’s incorrect.

The Wall Street Journal’s Carol E. Lee delved into the topic this week, quoting members of both parties—including people from the president’s inner circle—on the strange punctuation.

Austan Goolsbee, the former chairman of the National Economic Council, told WSJ: “It's like 'forward, now stop.’ … It could be worse. It could be 'Forward' comma [raising the question] and now what?”

Even the president has joked about it, according to WSJ.
