Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'expand' (расширять) which focuses on volume/scope. 'Extend' is more linear (удлинять, продлевать).
- Do not use 'extend' for 'provide' in all contexts. 'Extend help' is correct, but 'extend information' is less idiomatic; 'provide information' is better.
Common Mistakes
- Incorrect: 'They extended the house.' (Use 'extended' for adding a room, but 'They built an extension' is more natural.)
- Incorrect: 'Can you extend me the book?' (Use 'pass' or 'hand').
- Incorrect preposition: 'extend in time' (correct: 'extend over time').

FAQ
Frequently Asked Questions
'Extend' typically refers to making something longer in space or time (linear). 'Expand' refers to increasing in volume, size, scope, or detail (multi-dimensional).
Yes, in patterns like 'extend someone an invitation' or 'extend them credit'. The direct object is the thing offered, and the indirect object is the recipient.
It is neutral but common in formal contexts. In very informal speech, synonyms like 'make longer' or 'stretch' might be used, but 'extend' is not overly formal.
The primary noun is 'extension'. 'Extent' is a related noun meaning the degree or scope of something, not the action.
