Place the description beside the right subject.
A descriptive phrase needs a clear connection to the word the phrase describes. Distance can make that connection uncertain. A revision should identify the intended relationship without adding unsupported facts.

A reader can often guess what a tangled sentence means. That rescue does not make the structure a good model for international writing. A descriptive phrase should give the reader a visible connection to the relevant person or thing. The placement of a modifier can determine whether that connection is clear, uncertain or accidentally comic.
Examine a published opening.
Nearly 25 years since its launch, data from this space-based solar observatory has led to the discovery
Nearly 25 years after SOHO’s launch, data from the observatory has led to the discovery
The source continues with the extent of the comet discoveries. The opening refers to a launch before naming the observatory, while the main clause begins with “data”. A reader familiar with the mission can identify the intended referent. My revision names SOHO within the time phrase and preserves “data” as the subject of the main clause. The change makes the launch reference explicit without inventing a new actor.
This opening is not a classic dangling participle. A temporal phrase can locate the event described by a whole clause, rather than describe the grammatical subject alone. The concern here is the delayed identification of the possessive reference. A useful edit should name the actual problem instead of forcing every awkward opening into the same category.
Recognise a genuinely dangling action.
Having finished the assignment, the TV was turned on.
Maya turned on the TV after finishing the assignment.
The introductory action needs someone who finished the assignment. The original main clause supplies a television instead of that person. My revision names Maya as the actor and keeps the sequence of events. Maya is an invented subject for this exercise, not a person identified by the source.
Purdue explains the dangling construction through the missing connection between the introductory action and the main-clause subject. A revision can name the actor or give the opening clause a subject of its own. The correct choice depends on what actually happened. A grammatical repair must not invent a person in a real report merely to make the sentence run smoothly.
Keep the description close.
The researcher interviewed the patient with a recording device.
The researcher used a recording device to record the interview with the patient.
The researcher interviewed the patient who was carrying a recording device.
The first sentence allows competing attachments for the final phrase. The device may be the researcher’s tool or a possession identifying the patient. The first revision assumes that the researcher used the device to make a recording, while the second assumes that the patient carried the device. Neither assumption belongs in a final edit without confirmation.
Underline a descriptive phrase in your own writing and identify the word or action the phrase concerns. Check whether another noun could attract the description. Move the phrase closer, or expand the structure so the relationship has an explicit subject. A reader should spend attention on your explanation rather than reconstructing the connections.
