A Caption with Austen on Nothing

"Expect a most agreeable letter, for not being overburdened by subject – having nothing at all to say – there shall be no check to my genius."

Zwicky apposes to the Austen quote
a keyword of communicative competence:

"The advantage of having nothing to say."

It's amazing how florid a caption can be
when it's notional.

For all the world positioned
as if to advantage.

"The roses were displayed to advantage in a blue vase."

As with the subject –
as if with the subject –
emphasis added.
