How Complex Verbs Acquire Their Idiosyncratic Meanings.
Sergei Monakhov
PMID 37772604WHAT IT FOUND
Native Russian speakers changed prefixes when verbs meant spatial actions and changed bases when verb meanings were unpredictable.
The way prefixes and bases predict each other in Russian text tracked how transparent verb meanings were.
Key findings
01In the word-production task, spatial verbs produced more varied prefixes, while non-spatial verbs produced more varied bases.
02A probability ratio comparing how well a base predicts its prefix with how well a prefix predicts its base correlated negatively with a corpus score for how much a verb's meaning could be built from its parts.
03A model using that probability ratio predicted compositionality scores more accurately than a model using derivation-to-base frequency ratios.

What it does not show
The paper says the potential impact of verb polysemy remains unaccounted for, so a verb with both spatial and non-spatial meanings can be hard to classify. The paper says it is unclear how the two-construction account covers Russian prefixes that do not have a matching free preposition. The paper warns that English and German examples should not mislead the reader, because the tested data are Russian. The study reports native Russian speakers and Russian corpus data, not patients, therapy, or communication outcomes.
The easy way to misread this
Do not read the significant verb-pattern results as proof that a therapy will help patients. The study tested native Russian speakers and Russian corpus data, not patients or therapy outcomes.
