Usage tips
Inseparable verb
'Überwintern' (to overwinter) is an inseparable verb because the prefix 'über-' is unstressed. It remains firmly attached to the verb in all sentence forms, and the past participle is formed without 'ge-'.
EXAMPLE
Der Igel überwintert in unserem Garten.
The hedgehog overwinters in our garden.
Word structure
The verb is derived from the noun 'der Winter' (winter). The prefix 'über-' here has the meaning of 'to get through something' or 'to make it through a period of time'. So 'überwintern' means to get through the winter.
EXAMPLE
Einige Schmetterlinge können als Falter überwintern.
Some butterflies can overwinter as adult butterflies.
Context clue
The subject of the sentence tells you which meaning is intended. If it is animals or plants, the biological meaning is meant. With people, it is about a long trip; with objects, it is about storage.
EXAMPLE
Der Igel überwintert im Laubhaufen.
The hedgehog overwinters in the pile of leaves.
Use with location
The verb 'überwintern' (to overwinter) is very often combined with a prepositional phrase that indicates the location. Typical prepositions are 'in', 'an', or 'auf'.
EXAMPLE
Die Kraniche überwintern in Südeuropa.

überwintern vs unterstellen
to impute / shelter / subordinate
'unterstellen' and 'überwintern' can both have to do with a sheltered place. However, 'unterstellen' usually means protection for a short time, for example from rain or sun. You put yourself or an object underneath something. 'überwintern' means that animals, plants, or objects stay in a suitable, sheltered place for the whole winter. The words can be confused because both express protection. The important difference is time: 'unterstellen' is usually short-term, while 'überwintern' lasts through the winter months.
