adjective
British English
- The xiphisternal junction was clearly visible on the scan.

Learning
Memory Aids
Mnemonic
Think 'X marks the spot' at the bottom (the 'tip') of the sternum. 'Xiphi-' sounds like 'zippy', and it's the zippy, pointed end.
Conceptual Metaphor
Often metaphorically described as a 'sword tip' or 'dagger' due to its shape and the Greek root 'xiphos' meaning sword.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct translation might be attempted as 'мечевидный отросток грудины' (mechevidnyy otrostok grudiny), which is the correct anatomical term, not a calque of 'xiphisternum'.
Common Mistakes
- Misspelling as 'xiphesternum' or 'xiphistenum'.
- Confusing it with the 'manubrium' or 'body of the sternum'.
- Using it in non-anatomical contexts.
