覚え方のコツ Memory Tip
まず south「南」+ east「東」+ -ward「〜の方へ」と3つに分けると覚えやすいです。-ward が付くと toward, eastward, homeward のように「方向」を表す副詞になりやすく、southeast だけより「南東のほうへ進む」感じが強まります。地図を見て head southeastward, drift southeastward, spread southeastward など、進路・雲・風が南東側へ向かう場面と結び付けると定着します。southeastern（南東の、形容詞）との違いにも注意。
Break it into `south + east + -ward`. The ending `-ward` often shows movement or direction, like `homeward` or `eastward`. Remember it with map verbs such as `move southeastward` or `drift southeastward`, and do not confuse it with `southeastern`, which is an adjective.

southeastward の語源・成り立ち Etymology
「southeastward」は古英語由来の south「南」+ east「東」+ -ward「〜の方へ」から成る語です。意味は文字どおり「南東のほうへ」で、方角を一枚ずつ積み上げて作る英語らしい透明な複合語だと分かります。関連語はeastward、southward。
"Southeastward" is a transparent English compound built from "south," "east," and the suffix "-ward," meaning "toward." "South" and "east" both come from Old English, and "-ward" is also an old native English ending. The word developed in a very literal way: it simply means movement in the direction made by combining two compass points, like "eastward" and "southward."
