Please consider:
- Without so much as a call or a letter – he showed up.
Is sentence (1) above not only grammatical in syntax and morphology, but also acceptably punctuated according to guidelines for standard written English worldwide?
I know that dashes can be used to emphasize parenthetical information, but I feel as though the parenthetical element typically comes either within an enclosing set of dashes or else after a single dash, not before one. After all, dashes typically draw attention to and emphasize what comes after (or within).
Therefore, does placing a dash after a parenthetical element still draw attention to that parenthetical element, or does it draw attention to the independent clause which follows it?
Is it even good style to use a dash in a sentence with a parenthetical element in order to emphasize the independent clause rather than the parenthetical one?
Here’s an example of what I’m wondering about:
- He showed up – without so much as a call or a letter.
Here the emphasis is on without so much... in sentence (2) above, isn’t it?
And wouldn’t that be different from this?
- Without so much as a call or a letter – he showed up.
Because here in sentence (3) the emphasis is on ...he showed up, isn’t it?
But is this stylistically appropriate for sentences with this grammar?
