Prefix stacking and order
Recognise that possible multi-prefix forms differ in naturalness and register.
Russian can stack prefixes, but order, meaning, lexical convention, and register constrain the result. Formal possibility does not guarantee neutral usage.
- переподписать: sign again.
- недооценить: underestimate.
- Highly stacked forms may be technical, playful, or marked.
Mini-check
Does formal word-building possibility guarantee ordinary naturalness?
Advanced pattern
Marked multi-prefix formations are useful evidence about structure but are poor beginner production targets.
