Grammar Patterns

[verb] + free of + noun phrase

Usage Note

Often paired with verbs that describe movement away from something: 'break free of', 'pull free of', 'wrench free of', 'come free of'. The phrase usually follows the verb rather than preceding it. This sense expresses physical separation only, not figurative release from an obligation (which uses 'free from').

Common Mistakes

The bird flew free of the cage' (when meaning it was released from captivity).
The bird flew free of the netting it had been tangled in.
Use 'free of' for physical entanglement; use 'free from' for captivity or obligation.
