When you are in Valencia (or anywhere else in Spain for that matter) you will come to the conclusion that your English is not going to help a lot. In Valencia there are two official languages spoken:
1. Castilian
2. Valenciano
Most people are proud of their Valenciano language and speak it among each other, but they all speak Castilian as well. If somebody starts speaking to you in Valenciano, ask them if they can speak Castilian and they will change language.
To help you a little bit, we have made a basic vocabulary list in Castilian and Valenciano, so you won’t feel like a fish on the dry.
