I am using the Sogang online Korean program and have a question concerning this verb.
The lesson says:
Tense and negation are contained in 고 싶다.
In terms of tense it gave this sentence as an example:
피자를 먹고 싶어요-I wanted to eat pizza.
But when I read it, it seems to me that that sentence could also mean "I want to eat pizza." From what I've learned wouldn't "I wanted to eat pizza" be something like this:
피자를 먹고 싶었어요
could it just be a typo in the lesson?
Also in terms of negation it gave this sentence as an example:
피자를 먹고 싶지않아요-I don’t want to eat pizza.
I understand the concept pretty well, except for the 지 added after 싶 Why was that added?
If someone could clear these questions up I'd appreciate it!
