I also dabble on some of the other Wiktionaries (Spanish, German, Arabic) adding and augmenting translations.

- I can read Spanish and French pretty fluently. Because of that I can also understand a lot of written Portuguese and Italian, too.
- With difficulty and/or with a dictionary, I can read German, Latin, Ancient Greek, Russian, Arabic, and Persian.
