Choose the right word
unwise, imprudent, injudicious, ill-advised
These terms are all used to criticize a person or their behaviour as foolish; they generally suggest that the person should have been capable of taking a more sensible decision, if they had been prepared to think more carefully.Unwise is typically used with an impersonal it and followed by an infinitive ( it would be unwise to try and fight). Besides indicating foolishness, it may be applied to an intellectual judgement that is merely not justified ( it would be unwise to see the Jacobite unrest as typical of public opinion at the time).Imprudent emphasizes a person's failure to think of the future, and it is often used in financial contexts ( it would be imprudent to leave her winter coat behind | the banks made hundreds of imprudent loans in the 1970s).Injudicious is a relatively formal word. It is typically used of an action, rather than the person performing it, and not followed by an infinitive ( he will probably pay dearly for his injudicious comments).Ill-advised is typically used to describe an action and implies that others could have warned the perpetrator of the consequences of their folly ( the strike was ill-advised and would play into the hands of the management | you would be ill-advised to go on your own).
