southeast
The compass direction that lies exactly between south and east.
Der Kompass zeigt genau nach Südost.
The compass points exactly southeast.

'Südost' (southeast) is a compound word made from the compass directions 'der Süden' (the south) and 'der Osten' (the east). This pattern applies to all intermediate compass directions, such as 'Nordwest' (northwest) or 'Südwest' (southwest).
Die Hütte liegt in Richtung Südost.
The hut lies in a southeasterly direction.
To indicate a direction, you use 'nach Südost' (toward southeast). To describe origin, you say 'aus Südost(en)' (from the southeast). A position in a region is expressed with 'im Südosten' (in the southeast), with the ending -en.

When 'Südost' (southeast) describes a geographic region, it often appears with the definite article and a 'von' phrase, e.g. 'der Südosten von Spanien' (the southeast of Spain). As a pure direction, it usually appears without an article after a preposition like 'nach' (toward).

southwest
'der Südwest' and 'der Südost' both refer to a direction or an area in the south. The important difference is the second direction: 'Südwest' lies between south and west, while 'Südost' lies between south and east. They are easy to confuse because both begin with 'Süd-' and sound similar. So pay attention to the second part of the word: '-west' points toward the west, and '-ost' points toward the east.
