lääkäreihin
lääkäreihin is the illative plural form of the Finnish noun lääkäri, meaning the doctors. In Finnish, the illative case expresses direction or destination, so lääkäreihin is used to indicate moving toward or contacting a group of doctors. The singular illative would be lääkäriin (to a doctor). The plural stem undergoes a vowel change from lääkäri to lääkäre- before adding the illative plural suffix -iin, yielding lääkäreihin. This form is common in everyday Finnish and appears in contexts such as visiting a clinic, consulting a group of physicians, or directing actions toward doctors collectively.
In usage, lääkäreihin typically follows verbs of movement or communication. For example, Menen lääkäreihin means I
