I’m mainly talking about watching a TV show or movie that’s originally in English enabling subtitles that’s either in Spanish, German, Russian, Finnish, etc. and can mistakes in translation still occur? I recall watching Lie to Me with Japanese subtitles during a scene involving an interrogation but a key word within the dialog was not translated correctly based on context.
For example, the protagonist said “You’re an accessory for murder” towards the suspect but subtitles used the wrong word choice 小物 (which means “accessories” as in small goods, i.e. stationery or trinkets) when the intended meaning for “accessory” from that context leans more on being a conspirator (共犯者 or 共謀) of a crime (like as in aiding the criminal).
I kinda feel this if I turn on both subs and dubs on an anime. Sometimes they’re different, and you can see where one chose a straight translation where the other tried to convey some idiomatic meaning lost in the literal translation. It’s interesting to note the differences, and try to figure out the original meaning by comparing them.
