Prepositional Verbs: penser à, avoir besoin de, s'intéresser à
Prepositional Verbs: penser à, avoir besoin de, s'intéresser à
English verb-preposition pairings are already often arbitrary and don't translate word-for-word into French — 'think about' uses 'about', but French uses à; 'need' takes no preposition at all in English, while French avoir besoin requires de. These pairings have to be memorized as fixed units rather than assembled logically by translating the English preposition.

penser à vs. penser de — two different meanings
Je pense à toi. vs. Que penses-tu de ce film ?
I'm thinking of/about you. vs. What do you think of this film?
penser à means to have someone/something in your thoughts or to focus your mind on it; penser de is used only when asking for or giving an opinion. English 'think about' vs. 'think of' is a similarly subtle native-speaker distinction, but the French split doesn't line up neatly with the English one — don't mechanically translate 'about' as à and 'of' as de; instead, ask whether the sentence is about mental focus (à) or evaluation/opinion (de).
avoir besoin de — a completely different sentence structure from 'need'
J'ai besoin de temps.
I need time.
English 'need' is a plain transitive verb with no preposition at all. French avoir besoin is literally 'to have need of' — a noun phrase (besoin, 'need') that structurally requires de before its object. There's no way to derive this de from the English sentence, since English 'need' doesn't involve a preposition in the first place; the whole construction has to be learned as a unit: avoir besoin de + noun/infinitive.
s'intéresser à — a different preposition from English 'in'
Je m'intéresse à la musique.
I'm interested in music.
English pairs 'interested' with 'in'; French pairs s'intéresser with à. There's no logical way to predict this from the English preposition — memorize the verb and its preposition together as a single unit, the way you'd memorize an idiom.
A short reference list of other common mismatches
assister à un cours / manquer à quelqu'un / jouer à un sport vs. jouer de la guitare / rêver de / se souvenir de
to attend a class / to be missed by someone / to play a sport vs. to play the guitar / to dream of / to remember
assister à means 'to attend' (not 'to assist' — a false friend). manquer à has a reversed subject-object structure compared to English: tu me manques literally means 'you are lacking to me' but translates as 'I miss you' — the person doing the missing in English becomes the indirect object in French, and the person missed becomes the subject. jouer à is for sports/games, jouer de is for musical instruments — English 'play' uses no preposition distinction at all for this difference. rêver de ('to dream of/about') and se souvenir de ('to remember') both need de where English sometimes uses 'of' and sometimes no preposition ('remember' takes a direct object in English, with no preposition). Treat each of these as its own flashcard rather than trying to derive it from the English translation.
