| Usage notes | Use 'attachment' in a variety of contexts, like emails (an attached file) or emotional connections. Avoid using it in very casual settings where a simpler word would suffice. | Use 'connection' in both social and technical contexts. Avoid using it in overly casual situations, where simpler terms might be more appropriate. | Used in both physical and digital contexts. In formal contexts, use 'document' or 'record' for specificity. Avoid using 'file' to refer to a single item unless specified. | Use 'link' in both formal and informal situations.
