psyykkisten

Psyykkisten is a grammatical form in Finnish, most commonly the genitive plural or partitive plural form of the adjective psyykkinen, which means "psychic," "psychological," or "mental." As a modifier it is used to indicate possession, relation or attribution to multiple entities: for example, psyykkisten toimintojen tutkimus ("study of mental functions") or psyykkisten häiriöiden hoito ("treatment of mental disorders").

The adjective psyykkinen derives ultimately from the Greek root psykhē (soul, mind) through European scientific vocabulary, and it entered Finnish via international loanword channels. Morphologically, psyykkinen declines according to standard Finnish adjective patterns; psyykkisten is the genitive plural (also used as part of some compound or attributive constructions), while related forms include psyykkisyys (the noun "psychicity" or "psychological nature") and psyykkisesti (the adverb "psychically" or "mentally").

Usage occurs across psychology, psychiatry, education, occupational health and legal contexts to describe mental processes, conditions, capacities or impacts. In everyday Finnish the word often overlaps with henkinen, which can carry broader senses of spiritual or emotional aspects; choice between terms depends on clinical precision and context. Care is taken in professional and public discourse to use non-stigmatizing language when referring to people with mental health conditions.
