Conceptual Metaphor

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'изотерма' (isotherm) which is the general term. 'Изотера' is a direct but highly specialized equivalent.
Common Mistakes
- Confusing it with 'isotherm' (general) or 'isocheim' (winter).
- Mispronouncing the '-there' as /ðɛə/ instead of /θɪə/ or /θɪr/.
