Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'этиология' (direct cognate, same meaning). Be careful not to confuse with 'этикет' (etiquette) or 'этика' (ethics) due to similar spelling in Russian.
Common Mistakes
- Misspelling as 'etymology' (the study of word origins).
- Using it in casual conversation where 'cause' or 'reason' would be appropriate.
- Incorrect stress placement (stress is on the third syllable: ti-OL-o-gy).
