The plural form is lacunae or lacunas; adjectival form lacunal.(pr. lə-KYOO-nə)Example:Roman, Alexander the Great and Darius III in Battle, mosaic mural. Over its long history this important work has endured tremendous damage. Although art conservators have been able to stabilize it, and even repair some of its damaged areas, some lacunae have proven too difficult to refill. The result is that many must remain. Intentionally some restored areas were made in a way that reveals them as repairs. Also see art history, ellipsis, inpaint, letter spacing, kerning, placeholder, and shard.
