Checkout Learncraft Spanish. The step they take to simplify that others do not is that they focus knly on grammer for a very lokg time, and just use english verbs and nouns.

For example, at a certain point the only words you will have learned are que and lo, so the quiz sentances will be like :

I want you to eat it -> I want que lo you eat

This prpgram has been extremely useful to me and helped me learn spanosh far quicker than other methods. They also use memory palace techniques and have an unusually effective way of organizing vocab learning
