easternmost

the word "easternmost" is a modern english compound formed by combining the adjective "eastern" with the superlative suffix "-most." "eastern" itself derives from old english "ēast," meaning "east," which has proto-germanic origins and is related to the dawn and the rising sun. the suffix "-most," used to form superlatives of direction, evolved from the old english "-mest," a double superlative incorporating the old english "-ma" and "-est." therefore, "easternmost" literally and logically means "most eastern" or "farthest toward the east," precisely describing the extreme geographical position.

Structure: eastern + most "eastern" (from old english 'ēasterne', meaning "of the east"; an adjective-forming suffix) + "most" (from old english '-mest', a superlative suffix).
