Synonym discussion
Sense: adjective/1
"East" and "eastern" are the most common pair. "East" usually appears in fixed or formal names (East Africa, East Coast, East Germany) and in precise location phrases (east of the river). "Eastern" describes a broader, less precisely bounded area — you are more likely to say "eastern part of the city" than "east part." "Easterly" mainly describes direction of movement or wind (an easterly breeze, travelling in an easterly direction). "Eastward" and "eastwards" describe movement toward the east without focusing on origin (they drove eastward through the night). A practical test: if you can replace the word with "east of" and keep the meaning, use "east"; otherwise, "eastern" is usually the right choice for general area descriptions.

Etymology
From Old English ēasterne, formed from ēast (east) plus the suffix -erne (indicating direction). The word has cognates in Old High German ōstrōni and Old Norse austrœnn. The cultural sense (Eastern world / Asia) emerged from the historical European perspective, where major trade routes and civilizations lay to the east.
