The profound influence of Latin upon the genesis and development of English medical terminology is undeniable and well-grounded [1,2,3]. Approximately 95% of English terms are borrowed from or created on the basis of Latin and latinized Greek [4]. Therefore, the English medical terminology cannot be “reasonably mastered without the knowledge of basic Latin” [5]. Within the English terminological system, Bujalkova and Dzuganova distinguish (1) Latin terms that were assimilated into English (anglicized Latin terms, such as “muscle,” “vein,” “nerve,” and so forth), (2) terms that experienced a multiple assimilation (from Greek into Latin, from Latin into Old French, from Old French into English; for instance, “spasmos” − “spasmus” − “spasme” − “spasm”), and (3) terms preserved in the original Latin form (“vena,” “dorsum,” “nucleus,” and so forth) [2]. The last-mentioned group of terms are preserved in the original Latin form up to the present but have undergone certain modifications in terms of pronunciation in accordance with English phonetic rules. Therefore, we suggest referring to this group of lexis as semiassimilated terms. In addition, we consider it necessary to distinguish the nonassimilated Latin terminology, represented by multiple-word terms that preserve the original features of the Latin grammatical system, such as the relationship between the parts of speech, agreement in gender, inflection rules, and so forth (for example, per os, cor pulmonale, os ischii, musculus latissimus dorsi, and the like).
