According to Your Dictionary and MacMillan Dictionary, The abbreviation EST can either stand for Eastern Standard Time, estimated, or established. Eastern Standard Time refers to Greenwich Mean Time, or GMT -5:00. You might see est mean “established” in front of a year. If a company was established in 1920, they might put “Est. 1920” below their company name on a sign or building. Est can also be used as a native English suffix, added to the end of words to create a superlative degree of most adjectives and adverbs, such as “great” becoming “greatest.” Est is also an obsolete Old English noun that means grace or favor, and can be used as a verbal ending to form the archaic second person verb ending form of English verbs.
