Participle Swarm

Flags sentences with multiple simultaneous "-ing" actions or "as/while" constructions that imply physically impossible concurrent actions.

What It Does

Detects two patterns:

  1. Opening participle clusters: Three or more VBG (gerund) actions stacked before the main subject ("Unlocking the door, putting on his coat, and walking downstairs, he sighed.")
  2. "As/while" double-ups: Two or more simultaneous action markers in one sentence with concurrent gerunds.

Why It Matters

This is known as the simultaneous action fallacy — characters can't physically perform multiple complex actions at the exact same instant. Opening participle swarms also weaken prose by delaying the subject and creating a monotonous rhythmic pattern.

What Gets Flagged

Severity Example Why Suggested Revision
Information "Unlocking the door, putting on his coat, and walking downstairs, he sighed." 3 simultaneous -ing actions "He unlocked the door, put on his coat, and walked downstairs. Then he sighed."
Hint "She smiled as she drank the water as she walked to the door." 2 "as" simultaneous markers "She took a sip, smiled, and walked to the door."
