Commas with Participial Phrases
Good writing is about more than grammar and punctuation. It's about great characters, difficult decisions, high stakes, and insight into the human condition. But...it's also about good grammar and punctuation. Sometimes, important marks gets omitted, like the poor little comma in the illustration here. Perhaps the omission is in the effort to make writing smoother. Unfortunately, it often has the opposite effect. Here's one type of common omission..
When you have an independent clause (“Nathan stumbled along
in front of the guard”), followed by a dependent clause starting with an "–ing" verb (“looking for ways to escape”), ask yourself whether you can stick who was/that was in the middle. Does it still make sense?
Example 1:
Test: Nathan shuffled
along in front of the guard WHO WAS looking for ways to escape. Um…the guard was looking for ways to escape? No, Nathan was looking for ways to
escape. You therefore need a comma in
the middle to indicate that the subject of the first clause is also the one
doing the second clause.
Correct: Nathan
shuffled along in front of the guard, looking for ways to escape.
Incorrect: Nathan shuffled
along in front of the guard looking for ways to escape.
Example 2: I sat on
the sofa sagging in the corner.
Test: I sat on the
sofa THAT WAS sagging in the corner.
Makes sense. No comma.
Example 3: I sat on
the sofa massaging my ankle.
Test: I sat on the
sofa THAT WAS massaging my ankle. Cool
sofa! I want one. But really, that’s not what you meant at all.
The sofa wasn't massaging your ankle. You were. So you need the commas before the –ing.
Correct: I sat on the
sofa, massaging my ankle.
Example 4: “Come pick me up,” Sarah demanded through the phone
looking in horror at the fire.
Test: “Come pick me
up,” Sarah demanded through the phone THAT WAS looking in horror at the fire. Hmm…that's a really smart phone.
Correct: “Come pick
me up,” Sarah demanded through the phone, looking in horror at the fire.
Use the "THAT WAS" test:
If you can stick that was in the middle and it still
makes sense, no comma.
If you stick in that was and it changes the meaning, put
a comma between the clauses.
Note: It works in
other situations too. Other adjective or
participial phrases modifying a subject earlier in the sentence have this same
comma pattern.
Example 6: She
continued pushing dirt down around the seedlings oblivious to the threat at her
front gate.
Test: Liz continued
pushing dirt down around the seedlings WHO WERE oblivious to the threat at her
front gate. Technically, the plants were
oblivious, but you probably mean that Liz was oblivious.
Correct: Liz continued pushing dirt down around the seedlings, oblivious to the threat at her front gate.
Correct: Liz continued pushing dirt down around the seedlings, oblivious to the threat at her front gate.
Often this mistake just requires
that your reader pause a moment and re-evaluate, but sometimes it leads to mass
confusion. "John walked up to the man kissing
the belly dancer." Obviously the man was kissing the belly dancer. If you meant that John was kissing the belly dancer, your readers aren't going to understand, so put in the comma.
NOTE: If you're a person who doesn't use any commas unless absolutely necessary, you can sometimes omit this comma. However, if there's any possibility that your reader will misunderstand, it's best to follow the rule and include it.
