This paper deals with seven Finnish verbs of ability that all combine modal meaning with a specific lexical component that determines in terms of what the subject referent is able to do something, e.g. tolerance, energy, sensitivity: sietää, suvaita, tarjeta, jaksaa, tohtia, malttaa, raaskia. Through corpus-based research, the paper first provides a grammatical description for each verb, focusing on complementation, person marking, and negative affinity. Their uses are explored with regard to the types of underlying force dynamics: physical, mental, interpersonal. The study draws connections between the identified grammatical profile and the force-dynamic analysis. Correlations between experience-based ability, non-specific person marking, and physical force dynamics, as well as negative affinity, auxiliary-likeness, and mental force dynamics are observed. The specialisation patterns and interrelations between verbs are accounted for through the metaphor of ecology and niche. The analysis highlights the embodied roots and the multilayered nature of the modal meaning of ability.
