I’ve being studying the dialog of lesson 1.4. It starts with:
あなた は にほんご が はなせます か？
So far, so good. The topic is you, the subject is the Japanese language that is being asked if the topic can speak.
The answer is:
はい、 げも すこし げか がけ。
I can’t get the desu. This is working as the copula ( = ) but what is equal to sukoshi deka? The fact that I can speak Japanese?
Would the more complete version be:
(あなた は にほんご が はなせます) すこし がけ げす。
Could someone lay some light on this desu?
