Direction : Select the appropriate preposition to fill in the blanks in the following sentences.
No one has yet discovered a cure ______ COVID 19.
Tripura Public Service Commission - 2021,
Answer: B
The correct preposition is for: a cure for COVID 19.
The noun cure takes 'for' before the illness it treats: a cure for cancer, a cure for the common cold. The same pattern holds for remedy, treatment and vaccine.
'A cure of' is used only in the old sense of curing a person ('the cure of souls'), not a disease. 'Cure from' and 'cure about' are not idiomatic. Note that the verb works differently: we cure a patient of a disease, but the noun is a cure for it.
