A more thorough explanation:

Definition: Alleged (pronounced uh-lejd) is an adjective used to describe something that is claimed to be true, but has not yet been proven or confirmed.

Examples:

• The alleged thief was caught on camera stealing from the store.
• The alleged cheating scandal rocked the school and caused many students to question the integrity of their peers.
• The alleged murderer was arrested and taken into custody, but has not yet been tried in court.

The examples illustrate how the term "alleged" is used to describe something that is claimed to be true, but has not yet been proven or confirmed. In the first example, the thief is only alleged because they have not been caught or convicted. In the second example, the cheating scandal is alleged because the truth has not yet been fully investigated or confirmed. In the third example, the murderer is alleged because they have not yet been tried and found guilty in a court of law.
