| Usage notes | Use 'constant' when discussing something that remains unchanged over time. It can be used in both formal and informal contexts, but is often used in academic or scientific discussions. | Use 'fixed' when something has been repaired or when it's stable and unchanging. Avoid in casual conversations unless referring to repairs or adjustments. | Use 'steady' to describe something that is consistent or reliable. It’s appropriate in both casual conversations and professional contexts, but avoid using it in overly emotional situations. |
