To be magnanimous is to be nobly generous rather than petty in feelings or actions. Hmmm, I do try to behave with magnanimity, but sometimes I get annoyed and fail to react magnanimously.
Do you like this word? It's a bit of a tongue mangler, isn't it? Decidedly tricky to illustrate too.
Umm... Aha! If someone who'd annoyed me fell into the sea I'd probably be magnanimous enough to throw them a life bouy – if I didn't have to go far to find one and I wasn't busy or anything.
