"I own this."

Translation: Fi sy biau hwn.

[tachwedd]

I translated this as 'Fi sy biau hwn' but it was marked as wrong but 'fi sy biau hon' was given as the correct answer. Surely it depends on the gender of what you're referring to?

[ibisc]

It should accept any of hwn (masculine), hon (feminine) or hyn (abstract or undetermined). The sy should be optional.

Diolch yn iawn!
