ocorr

Could you clarify what you mean by "ocorr"? It isn’t a widely recognized term on its own, and it could refer to different things in different contexts (for example a language-related root, a place or organization, or a specific acronym). If you provide the intended context or domain, I can draft a concise, neutral wiki-style article (under 300 words). If you’d prefer, I can also produce a disambiguation-style stub that covers the most common interpretations.
