Both translate as 'for' — but por looks back at causes and para looks forward to goals.

Both mean 'to know' — but saber is for facts and skills, conocer for people and places.

Both describe the past — but preterite is for finished actions, imperfect for what was ongoing, habitual, or in the background.

Add me, te, se, or nos when the action comes back to you — and nothing when it acts on an object.

IOP first, DOP second — and le/les change to se before lo, la, los, or las.

Me, te, le, nos, les — the pronouns that show who receives the benefit of the action.

Lo, la, los, las — replace the noun that receives the action, matching its gender and number.

Gustar flips the sentence — the thing you like is the subject, and you're just the indirect object.
