An "allegation" is a claim or assertion that someone has done something illegal or wrong, typically made without proof at the time it is stated. Allegations can arise in various contexts, such as legal cases, workplace disputes, or public controversies. They often require investigation to determine their validity. In legal terms, an allegation is not a proven fact; it is simply a statement that needs to be substantiated with evidence. For example, in a court case, a plaintiff may make an allegation against a defendant, and it is the responsibility of the legal system to evaluate the evidence presented.
