How to use "fall through"

What Does "fall through" Mean?

• The phrasal verb "fall through" means to fail to happen or not succeed. This often refers to plans, deals, or arrangements that don't come to fruition.
• The meaning is semi-idiomatic. While "fall" suggests a decline or failure, and "through" implies a lack of completion, the combination creates a specific meaning beyond the sum of its parts.
• The register is generally neutral, suitable for both formal and informal contexts.

How to Use It

• Grammatical pattern: verb + particle (phrasal verb).
• Typical subjects include: plans, deals, arrangements, proposals, support, etc.
• The components cannot be separated. You wouldn't say "fall the deal through," for example.
• What sounds unnatural: Using the wrong preposition (e.g., "fall down" instead of "fall through" when referring to plans), using the wrong verb (e.g., "collapse through"), or attempting to separate the phrasal verb.
