Gerunds and Infinitives: Need and Want (Passive Meaning)

When the subject of need is a thing (not a person), the gerund creates a passive meaning. "The car needs washing" means "The car needs to be washed" — someone should wash it. This is shorter and more natural in everyday English than the full passive form. Similarly, "This shirt needs ironing" means "This shirt needs to be ironed." The thing (car, shirt) receives the action; it does not do the action itself.

The same pattern works with require and deserve: "This problem requires thinking about carefully" and "She deserves promoting" (she deserves to be promoted). When the subject is a person, the normal infinitive pattern applies: "I need to wash the car" (I will do the washing). Compare: "The floor needs cleaning" (passive — something must clean the floor) vs "I need to clean the floor" (active — I must clean it). This passive gerund construction is commonly tested in Cambridge B2 First examinations.
