Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque from Russian 'несвязность' for all contexts; 'incoherency' is more formal and specific than general 'бессвязность'.
- Do not confuse with 'inconsistency' (непоследовательность), which is about contradiction over time, not lack of logical connection at one point.
Common Mistakes
- Misspelling as 'incoherancy' or 'incoherancy'.
- Overusing 'incoherency' where simpler words like 'confusion' or 'mumbling' would suffice in informal contexts.
- Using it as a countable noun for a single unclear statement (better: 'an incoherent remark').
