Memory Aids
Mnemonic
Think of 'BORT' on a car license plate – it's not the valuable, flashy car (gem), but it's still a functional vehicle (industrial tool).
Conceptual Metaphor
REJECTED THING AS A TOOL: A flawed or imperfect entity can still serve a valuable, practical purpose.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'борт' (board, side of a ship/vehicle). They are false friends.
- There is no direct one-word Russian equivalent; a descriptive phrase like 'технический алмаз' or 'алмазный порошок' is needed.
Common Mistakes
- Misspelling as 'bought' or 'bortz'.
- Using it as a general synonym for 'rubbish' or 'waste' without the industrial utility aspect.
- Pronouncing it to rhyme with 'short' (it rhymes with 'port').
