When using Where are Your Keys? to learn a language, we use Technique: Travel's with Charlie to describe different levels of language skill, based on the ACTFL scale.
Here is my translation of this scale for Palestinian Arabic:
Level 1 - Tabouli Babaghanoujh Hummos.
Level 2 - How to make hummos.
Level 3 - Explain why olive oil is so good for you.
Level 4 - Negotiate peace if the Middle East.
To put it another way:
Level 1 - Eat Arabic food
Level 2 - Make Arabic food
Level 3 - Why Arabic food
Level 4 - Get everyone to eat Arabic food
