Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'надпочечная железа' in English texts; use only 'adrenal gland'.
- Do not confuse 'adrenal' (adj.) with 'kidney' (noun). 'Adrenal' specifically refers to the gland on the kidney.
Common Mistakes
- Mispronunciation: /ˌæd.ˈriː.nəl/ instead of /ə.ˈdriː.nəl/.
- Misspelling: 'adrenaline gland' (the gland produces adrenaline but is not named that).
- Confusing 'adrenal' with 'renal' (renal = related to the kidney itself).
