The paper is focused on selected aspects of the contemporary Czech medical terminology, which appears to be relevant from the perspective of a lay user - native speaker of Czech (the teacher) and the student of Czech as a foreign language. It illustrates and comments primarily on terminological renderings of medical terms in lexical semantics of terms, their motivation, and (word-formation) structure (figurativeness, descriptive nature vs. economy), international character and dynamics (tradition vs. innovation).
