| Usage notes | Use 'maybe so' to express uncertainty or possibility. It's appropriate in casual conversations but might be too informal in formal discussions. | Use 'possibly' when you want to express uncertainty or doubt about something. It's generally neutral, suitable for both spoken and written contexts, but avoid it in very formal writing where you might prefer words like 'potentially'. |
