Green onions are said to be milder than onions, which would suggest that if one do not mind the more powerful onion flavour in a particular dish then onions could be used in place of green onions.
My assumption could be wrong here; I am not a chef but a poor father trying to cook. I want to substitute green onion for Escallion in some Caribbean recipes, and several internet sites say that Escallion is green onion – but, confusingly, some Caribbean cooking websites are saying that Escallion is not green onion.
Could someone clear this up for me? Is Escallion the same as scallions (green onions)? And can Escallion be replaced by onion in a recipe?

Escallion = scallion = green onion.
I think it's possible to substitute regular onions in some situations, but there are a lot of variables.
First off, scallions have a sharper, more grassy flavor than onions, though they're not as strong.
Then there's the question of which kind of onion you want to substitute. White onions have some of that same sharp flavor, and are quite strong. Yellow onions are much milder and sweeter, and might not be such a close flavor match. Red onions are somewhere in between, in my experience. I would probably try white onion, but in much smaller quantity than called for of scallions.
It's also important to consider how the scallions are being used. If they're being cooked into the recipe, that's very different than if they're being added right at the end, or even as a garnish. I think the substitution is less of an issue if the scallions are to be cooked. If they're to be more or less raw, I'd suggest white onion, not too much of it, and sliced very very thinly, as a raw white onion is really strong.
Whatever you try, bear in mind that it won't be exactly the same. But that certainly doesn't mean it'll be bad--just different.
