This German word doesn’t mean what you think it does. Forget nuts and bolts – it’s a sneaky label for someone with a wandering eye and zero shame.
You might grab a Spanner from your toolbox without a second thought, but in everyday conversation this noun can pack a very different punch.
What does Spanner mean?
Spanner, pronounced like this, is common German slang for a Peeping Tom or voyeur. The slang meaning is derived from the verb spannen, in the sense of “to watch closely” or “to spy on.”
Technically, it’s grammatically possible to talk about die Spannerin (a female Peeping Tom) in German, but for obvious reasons the word is overwhelmingly used in the masculine singular: der Spanner.
Spanner also means “wrench” or “spanner” in German just as it does in British English, originating from spannen in the sense of “to tighten.”
But most Germans are more likely to use the word Schraubenschlüssel in this context.
Why do I need to know Spanner?
Digital peeping – from hidden cameras and voyeuristic recordings to deepfakes and the non‑consensual sharing of intimate images – is a contemporary problem. It’s also one which has been discussed extensively in the German press recently because of a scandal involving two well‑known public figures.

But it’s still worth remembering that this crime didn’t begin with the internet. Sadly, voyeurism has arguably existed for as long as people have been around.
The English expression “Peeping Tom” is usually traced back to the medieval legend of Lady Godiva, who supposedly rode naked through Coventry to protest against high taxation.
According to some versions of the story, the townspeople averted their eyes out of respect – except for a man named Tom who watched though a secret peephole and was subsequently punished with blindness.
Germany’s Spanner isn’t that old, but the word is still quite venerable. It first emerged as part of an 18th century criminal argot known as Gaunersprache (crook’s language).
Originally, it referred more generally to spying or scouting something out – comparable to “casing a joint” – before acquiring its modern meaning.

Today, Spanner is used both on its own and as part of compound nouns, which frequently appear in tabloid headlines when a Peeping Tom is caught operating in a specific location.
Common examples include Sauna‑Spanner (sauna voyeur), Fenster‑Spanner (Peeping Tom at a window), and Balkon‑Spanner (a balcony‑based voyeur).
Use it like this:
Der Spanner hat wieder durchs Fenster geglotzt
The peeper was leering through the window again.
Pass auf, da drüben ist ein Fenster‑Spanner!
Watch out, there’s a Peeping Tom at the window over there!
