The English idiom ‘a match made in heaven’ is used to describe a couple who seem absolutely perfect together. They are so suitable for each other that it seems as though their relationship was preordained (arranged in advance) ‘in heaven’.
Olivia: Did you hear that Gerry and Eve have got engaged?
Greta: Yes! Isn’t it cute? I’m so happy for them. They’re so well suited.
Olivia: Yes, they’re such a perfect couple – and on Valentine’s Day too!
Greta: Aah. They’re a match made in heaven, I’d say.
