Frequently Asked Questions — Adjective + to…

Questions fréquentes — Adjectif + to…

When the subject of the sentence is the object of the infinitive (i.e. the subject IS what you understand), the pronoun is not repeated: ✗ He is hard to understand him. → ✓ He is hard to understand. Compare: ✓ It is hard to understand him (here 'him' is needed because 'it' is the subject).

Quand le sujet de la phrase est aussi l'objet de l'infinitif, on ne répète pas le pronom : ✗ He is hard to understand him. → ✓ He is hard to understand. Comparez : ✓ It is hard to understand him (ici 'him' est nécessaire car 'it' est le sujet).

Nice of you to come = you behaved nicely by coming (evaluates your action). Nice to you = kind/pleasant towards you (describes treatment): She was nice to me. The Unit 65 structure always uses of.

Nice of you to come = tu as été gentil de venir (évalue ton action). Nice to you = gentil envers toi (décrit un traitement) : She was nice to me. La structure de l'Unité 65 utilise toujours of.

Bound to = almost certain, unavoidable: She's bound to fail — she never studies. Sure to = certain: She's sure to pass — she works hard. Likely to = probable but not certain: It's likely to rain. All three are followed by to + infinitive.

Bound to = quasi-certain, inévitable. Sure to = certain. Likely to = probable mais pas certain. Les trois sont suivis de to + infinitif.

After ordinal expressions (the first, the last, the only, the next, the second…), English uses to + infinitive, not the -ing form: ✓ She was the first to arrive.She was the first arriving.

Après les expressions ordinales (the first, the last, the only, the next, the second…), l'anglais utilise to + infinitif, pas le verbe en -ing : ✓ She was the first to arrive.She was the first arriving.
