or with 'to' plus infinitive?

Watch this video to find out - you won't regret it.

'Regret' is a verb. It means

'to feel bad about a past action or situation'.

We often use it to talk about mistakes

we have made and feel bad about.

It can be followed by a noun:

'You'll regret that.'

Most commonly, we use 'regret' plus 'ing':

'I regret staying up so late last night. Now I'm tired.'

'Regret' plus 'to' plus infinitive

is only really used to make announcements

of bad news.

It's often found in formal letters, for example:

'We regret to inform you that your job application

has not been successful.'

At a train station or airport they might announce:

'We regret to inform you that the

16:10 to Scotland has been cancelled.'

Well, I don't regret any of this

and I hope you don't regret

learning about 'regret'.

See you.
