Attic (noun)

1. The space at the top of a building, under the roof, often used for storage.

Origin:

Late 16th century: from latin atticus "of or belonging to attica", from attica (the region of greece surrounding athens), on the pattern of words such as cretic, from creta "crete". the original sense was "of or belonging to athens", hence "pertaining to the top story of an ancient greek house" (which was used as a storeroom and often had a flat roof), later "the space at the top of a house or building".

Examples:

1. He stored old boxes in the attic.
2. The attic was converted into a bedroom.
3. She found her childhood memories in the attic.
4. The attic was insulated to keep the heat inside the house.
