Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation 'делать твёрдым' for abstract uses; better 'укрепить', 'закрепить' for relationships/support
Common Mistakes
- Using 'solidify' for emotional hardening (use 'harden' instead)
- Confusing with 'solidate' (not a word)
- Overusing in informal contexts where 'set' or 'harden' would be more natural

FAQ
Frequently Asked Questions
Yes, it commonly describes both physical processes (liquid to solid) and abstract processes (making plans definite, strengthening relationships).
'Harden' is more general and often physical; 'solidify' implies a transition from non-solid to solid state and is more common in formal/technical contexts for both literal and figurative uses.
It's neutral to formal; perfectly acceptable in academic and professional writing but might sound slightly formal in casual conversation where 'set' or 'harden' could be used instead for physical processes.
Yes, both transitive ('They solidified their plans') and intransitive ('The mixture solidified overnight') uses are correct.
