"Via kuzo neniam ludis tenison."

Translation: Your cousin never played tennis.

[AdityaTulahalli]

Does this mean "your cousin never has played tennis" or "your cousin never played tennis" (first one is like you're about to play tennis for the first time, and the second one emphasizes the past tense? Not sure how to explain it properly.)?

[SeanMero]

Yes, it means one or the other.
