Other forms: possibilities
A possibility is something that could happen but has not. Rain by the afternoon, a train delayed at Crewe, a job that might come up in the spring — each one is a possibility until it either happens or does not.
The grammar is where learners slip. It is the possibility OF doing something, or the possibility THAT something will happen; never the possibility to do. And a possibility is not an opportunity: if a friend offers you a free ticket, you have the chance to go, not the possibility to go. Ready-made phrases cluster around it — there is a strong possibility, a remote possibility, we cannot rule out the possibility. In the plural it turns hopeful and means untapped potential: the flat is small but it has possibilities, the possibilities are endless.
