Definition tell in British English

Unlike the verb say, the verb tell is usually used with a personal object, which refers to the person who is being told something:

✗ We know that what they are telling has already been said many times.

✓ We know that what they are telling us has already been said many times.

If you don’t want to mention a personal direct object, use say instead:

✗ As Rousseau told in his book, humans are good by nature, but society corrupts them.

✓ As Rousseau said in his book, humans are good by nature, but society corrupts them.

Don’t use the preposition to after tell to introduce the object (the person who is being told something):

✗ He told to journalists that he was innocent.

✓ He told journalists that he was innocent.

However, in some fixed expressions, tell can be followed by an object which refers to what is being told. The most frequent expressions are:

tell a joke, tell a lie, tell a story, tell the time, tell the truth

Tell can also be used with an infinitive to mean ‘to order someone to do something’. Don’t use say in this meaning:

✗ Who puts women in the kitchen, or says them to do the housework?

✓ Who puts women in the kitchen, or tells them to do the housework?
