～の後ろ

About

The noun 後うしろ can be used locationally to say that something is "behind" a given location.

Since 後うしろ is a noun, we can use the の particle to attach it to another locational noun.

E.g. パソコンの後うしろにリンゴがあります。
"There is an apple behind the computer."

～の後うしろ can be followed by the に particle as above, or the の particle, which creates a nominalized "noun phrase". Other particles, such as で or は are also possible depending on the sentence.

E.g. パソコンの後うしろのリンゴがおいしい。
"The apple behind the computer is delicious."

For its temporal usage, 後うしろ's reading changes to 後あと. More on this in the ～後あとで/に entry.
