A more thorough explanation:

EFFRACTION

Effraction is an old-fashioned word that means breaking into a place by using force.

1. The police found evidence of effraction at the jewelry store.

2. The effraction of the bank's vault was carefully planned and executed.

These examples illustrate how effraction refers to a breach or break-in that is done by using force. In the first example, the police found evidence that someone had broken into the jewelry store. In the second example, the effraction of the bank's vault was a carefully planned and executed crime that involved using force to gain access to the vault.
