What is the recommended survival vocabulary for Spanish speakers?
What is the recommended working vocabulary for Spanish speakers?

Fortunately, this is not an APA style question. Feel free to guess based on your native language.
I searched online also, and the amount of vocabulary varied a lot. In fact, the numbers ranged from 10,000 to 60,000 which are very different numbers. It would be interesting to know really what the average is.
