Punctuating Parenthetical Interjections Exercise (51)

Each of the following sentences includes an emphatic word that must be set off from the rest of the statement. Insert punctuation as necessary.

Answers and Explanations

1.
Original: An heirloom plant may have been grown in the same location for say a hundred years.
Correct : An heirloom plant may have been grown in the same location for, say, a hundred years.

Say, interjected into this sentence, must be bracketed by commas.

2.
Original: It’s within this context then that we must consider the arrival of the military advisers.
Correct : It’s within this context, then, that we must consider the arrival of the military advisers.

The transitional word then should be framed by commas.

3.
Original: Seemingly minor points could hamper the platform’s popularity, and, hence game sales.
Correct : Seemingly minor points could hamper the platform’s popularity and, hence, game sales.

Hence is the interjected word in this example; the only punctuation required is that which sets it off.

4.
Original: Keep solving for "x" and "y" with different numbers, until finally, you try 70.
Correct : Keep solving for "x" and "y" with different numbers until, finally, you try 70.

There’s no need for a comma preceding until, but one should follow it to match the comma following the interjection finally.

5.
Original: That process might even involve such old-fashioned ideas as, gasp!, putting search results in alphabetical or chronological order when requested.
Correct : That process might even involve such old-fashioned ideas as -- gasp! -- putting search results in alphabetical or chronological order when requested.

A dramatic interjection such as gasp! merits stronger signals of interruption.
