his·tor·ic (hĭ-stôrĭk, -stŏr-)
1. Having importance in or influence on history.
Usage Note: Historic and historical have similar, though usually distinct, meanings. Historic refers to that which is associated with significant events in history: the historic first voyage to the moon. Thus, a historic house is likely to be of interest not just because it is relatively old, but because an important person lived in it or was otherwise associated with it. In contrast, historical refers more generally to that which happened in the past, regardless of significance: a minor historical character in the novel, the historical architecture in the center of town. These distinctions are not always observed, however, and a historic tour of a city might include the same sights as a historical tour. Therefore, it is important to make sure that the context makes the intended meaning clear.
