Learning
Memory Aids
Mnemonic
Imagine the letters 'ISS' as a spaceship between 'International' (many flags) and 'Space Station' (floating home).
Conceptual Metaphor
A SHIP IN THE OCEAN OF SPACE (it has a crew, travels a set path, and is a self-contained vessel).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct word-for-word translation like 'International Cosmic Station'. The standard Russian term is 'Международная космическая станция (МКС)', so 'space' maps to 'космическая'.
- Remember it is a specific station, so the definite article 'the' is always used in English.
Common Mistakes
- Incorrect capitalisation (e.g., 'international space station').
- Omitting the definite article 'the' (e.g., 'He works on International Space Station').
- Misspelling 'Station' as 'Staion' or 'Space' as 'Spece'.
