An interesting Google Translate quirk
translate.google.com
translate.google.com
In this case, Google's approach confuses the latter for the former, because its corpus contains parallel texts that have not only been translated (into a different language), but also localized (into a different locale). For example, it may be extrapolating incorrectly from a French document and an English document with the following phrases in the same location:
FR Cliquez ici pour la version anglaise.
EN Click here for the French version.
This sign is another good example of how parallel texts are not always translations:http://flickr.com/photos/jadelin/2205088201/
(the Japanese "おかえりなさい" here means "Welcome home")
So:
"Nous parlons français ensemble." -> "We speak English together."
"Nous parlons français ensemble" -> "We all speak French"
"Nous parlons français." -> "We speak French."
"Nous parlons français" -> "We speak English"
Wir sprechen französisch zusammen
Jag kan inte prata svenska
turns into:
I can't speak English
If you're translating something like "Give it to me in plain English", you'd want the second meaning. Likewise, "It's Greek to me" doesn't hold the quite same weight when translated literally into Greek.
