I expect it has always happened, but I think it is much more prevalent now. I am speaking about the use of 'there's', when it is short for 'there is', being used instead of 'there are' or 'there're'. Have you had earlier threads about this? Here are some of this week's examples from Radio 4:-
- There's good examples of idioms........... Word Of Mouth, Dr. Gareth Carrol, 8.2.22
- There's going to be hundreds of thousands of people.......... More Or Less, 9.2.22
- There's other supply chains...... Today, 10.2.22
4.There's been some real issues......Brandon Lewis, 11.2.22
- There's some awful people out there......I'm not sure which programme, 11.2.22
Please tell me I'm not the only person VERY tired of what looks like trendy carelessness. (No, I don't sit all day writing them down, but I thought I would gather a few examples and get them off my chest here.)
