Hi!
« Agile » in English is also « agile »! Only the pronunciation is going to be different.
« Tyranosaurus » is already in English! :)
When you don't know how to translate a word, you can search on google translate or in an French-English dictionary! :D
If you have any other question, don't hesitate to ask! We'll be happy to help! :)
Laurie :)
