It is easier to think of the translations of these phrases in formal (or correct) English.
En lo que As far as
Con lo que with that which
Para lo que for that which
de lo que of that which
Por lo que because of what
a lo que to that which
And don't encourage bad English. "You can never place the preposition at the end of the clause like in English: Be careful what you wish for." You should never end with a preposition in English Be careful of that which you wish or Be careful for what you wish.
Hola Douglas L.
Using more formal English equivalents like “with that which” or “for that which” can indeed help highlight the underlying grammar of preposition + lo que, so your reasoning is understandable.
However, in our explanations we generally prioritise natural and commonly used English translations so that learners can easily relate them to everyday usage. Constructions such as “that which” are grammatically correct but quite rare in modern spoken English and they can sometimes make the explanation feel less intuitive.
Also, while traditional rules discouraged ending sentences with prepositions, this is perfectly acceptable in modern English and widely used by native speakers.
Thanks again for your thoughtful suggestion — feedback like this is always appreciated!
Un saludo
