In Italian, Spanish, Portuguese, and Catalan: the form of an adjective formed by adding the suffixes -issimo, -isimo, -íssimo, -érrimo, -imo, or -íssim to the adjective (with any final vowel dropped) to express a superlative that cannot be exceeded, having the sense “as ... as possible”.
In Greek: one of the degrees of comparison in an adjective that stresses an exceptional property without making a direct comparison, its closest equivalent in English being a most important letter, a very high mountain or absolutely pure water. It is formed by adding the suffix -τατος (declined) to the adjective's nominative, neuter singular.
In Romanian: The superlative absolute is formed with different adverbs preceding the actual adjective: foarte / tare / extrem de / cât se poate de + adjective.
