| Common mistakes | 'Add to' used incorrectly as if it were 'add with', Confusing 'add' with 'add up' which has different meanings, 'Adding' used without an object | Confusing with 'prepend' which means to add at the beginning., Incorrectly using with intransitive subjects, e.g. 'the data appends'. Should say 'the data is appended'. | Confused with 'detach' – forgetting to use the right prefix., Using 'attaching' incorrectly in passive constructions., Not following with an object, e.g., 'attach to' instead of 'attach the document to'. | 'Join' is often confused with 'meet' — they have different meanings., Learners forget to use 'join' with an object, saying 'I join' instead of 'I join the club.', Mixing up 'join' with 'attend' — attending can imply being present without being an active participant. |
| Usage notes | Use 'add' in both casual and formal contexts, but avoid it in very technical or academic writing where more specific terms might be required. | Used mostly in technical or formal contexts, such as programming or writing. Not common in casual conversation. | Use 'attach' for both physical and abstract connections, like emails or documents. Less common in very formal writing. Avoid with informal language unless using slang. | Use 'join' when indicating participation in an activity or becoming part of a group. It's neutral and can be used in both formal and informal contexts. Avoid using it in overly formal writing. |
