At least the "Transport > Teleport" effect (it's the only one I see in Wrath Classic — I was able to translate all the others into French —, but there may be others in Retail).

Oh, I see the issue for Statue: we using the same word in French, so I didn't see that the word wasn't translated! But thanks for the explanations!

Phew, thanks for finding that bug. And for translating in french! 🇫🇷

For some texts I'm using snippets from the game. That keeps the translation list fairly small. :)
For the "Teleport" I was using the spell name of [Teleport]. But that particular spell doesn't exist yet in WotLK. So the english original text gets chosen as fallback. Luckily there are several other spells to choose from. So no prob :)

Well.. for Teleport at least.
The same problem exists also for [Statue] and there are no direct alternatives in WotLK. So as alternative I'm chosing [Instant Statue]. There is only one Toy in that category anyway.
