Here is the recipes for the cookbook you are compiling for our children’s school fundraiser.
I see and hear sentences like these frequently. They contain an agreement problem. The subjects of the sentences are reasons and recipes, respectively. Both are plurals. But the introductory parts, There is and Here is, are both singular. You’re going to need There are and Here are. You can also use There’s or Here’s if the subject is singular.
When sentences start with There is, There are, Here is, Here are, the subject is always going to be the first noun following the introductory clause. The subjects are never There or Here. Therefore, if you use this construction, find the subject by looking at the first noun after it and use There is or There are and Here is or Here are accordingly. Easy, right?
