"Rising costs are compelling manufacturers to raise prices" -- is that the same "compelling" as "a compelling case"? No.
"Compelling" is usually an adjective (a compelling case), but it is equally the live present participle of the verb "compel" -- one thing actively pressuring another to act. These are two different jobs for the same word, not two flavors of the same job.
Telling the two apart structurally
As an adjective, compelling evaluates a thing's persuasive or attentional quality. As a present participle, "X is compelling Y to Z" reports one thing actively forcing or pressuring another -- common in ordinary business and news writing about market pressure, regulation, and competitive dynamics, not a specialized legal curiosity. The test is structural: if "compelling" is followed by an object plus "to + verb" -- compelling firms to raise prices, compelling the agency to disclose records -- it's the live verb form describing an action in progress. If it directly modifies a noun with no forced object-plus-infinitive structure -- a compelling case, the evidence is compelling -- it's the adjective.
Live verb-participle: "New competition from low-cost entrants is compelling established players to cut prices faster than planned."
Adjective, for contrast: "The audit findings are compelling" -- here nothing is being forced onto anyone; the findings simply carry persuasive force.

The mistake: reaching for the wrong job
The mistake is defaulting to the adjective when an actual forcing action is intended, or reaching for the plain verb "compel" when the meaning is really just "is persuasive." "The report compels" on its own is a misfire if the intended meaning is "the report is convincing" -- compel needs an object being forced to do something; the adjective is the right tool when nothing is literally being pressured into action.
Practice scenarios
Practice using compelling in situations like:
- describing market pressure or regulation forcing a company to act
- completing a sentence that needs the live verb-participle form, not the adjective
- distinguishing "compel" (force) from "compelling" (persuasive)
Useful practice phrases:
- "[Pressure] is compelling [companies] to [act]."
- "The data compel us to reconsider..."
- "The findings are compelling" (adjective, for contrast)
One word, two jobs: evaluating a thing's pull, or reporting an act of pressure.
