Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'адгезия' (adhesion), which is strictly physical/technical.
- Do not translate directly as 'приверженность' in all contexts; sometimes 'соблюдение' (for rules) or 'прием лекарств' (medical) is more accurate.
- Note the fixed preposition 'to' (adherence TO something).
Common Mistakes
- Using 'adherence for' instead of 'adherence to'.
- Confusing 'adherence' (abstract/behavioural) with 'adhesion' (physical sticking).
- Using in overly informal contexts where 'sticking to' would be more natural.
