Right way to learn prepositions

It is said that you can never end a sentence with a preposition at least formally, right? well what about this sentence: At what time do you want me to pick you up?
acording to the rule it should read: …to pick up you?
it sounds awful don’t you think?

Also, what is it with these phrasals that carry the preposition “up” just to boost the meaning or something,can you tell me a little more of this.

Is it too much or too continuos to ask?

in my country: no es tanto si no lo seguido.
meaning that whe a person is asking for too many things all at once you say that, of course humorously as a means of discourging the asking.

Hi Richard,

You can never ask to many questions - at least not here on this forum :slight_smile:
Could you please tell me where you read that you should never end a sentence with a preposition? Many questions containing phrasal verbs end with a preposition. Here are some examples:

What are you looking [color=blue]for?
How are you getting [color=blue]along?
What are you getting [color=blue]at?
Can you pick me [color=blue]up?
Would you like to come [color=blue]over?
