Vowel E
In medical Latin, the letter e is pronounced as the sound [e]. The main rule: unlike Russian, Latin consonants before this sound are never palatalized.
Examples of correct pronunciation:
- vértebra [vertebra] — vertebra;
- antérior [anterior] — anterior (it is incorrect to pronounce it as "anterior");
- artéria [arteria] — artery;
- mediánus [medianus] — median.
Letters I and J
The letter i has two pronunciation options:
- As the vowel sound [i]: for example, inférior [inferior] (lower), intérnus [internus] (internal).
- As the consonant sound [j]: this occurs at the beginning of a word or syllable before another vowel.
In modern medical terminology, the letter j (jot) is used to denote the [j] sound. It replaces i in the corresponding positions: juguláris [jugularis] (jugular), junctúra [junctura] (junction), májor [major] (major/greater), júgum [jugum] (jugum). To render the sound combinations [ja], [jo], [je], [ju], the combinations ja, jo, je, ju are used.
Important exception: the letter j is never written in terms derived from the Greek language, since Greek lacked the [j] sound. For example: iatrīa [iatria] (medical treatment), iódum [iodum] (iodine).
Letter Y and Greek roots
The letter y is named "upsilon" (or "ypsilon") and is pronounced as the [i] sound. It is used exclusively in words of Greek origin. The Romans introduced it to represent the Greek letter $\upsilon$ (upsilon). If the Greek original had the letter $\iota$ (iota), then i was written in Latin. Examples: týmpanum [tympanum] (tympanum/drum), gýrus [gyrus] (gyrus).
For accurate spelling, it is helpful to memorize common Greek prefixes and roots with the letter y:
- dys- [dis-] — impaired function (dysostósis — dysostosis);
- hypo- [hipo-] — under, lower (hypodérma — hypodermis, hypogástrium — hypogastrium);
- hyper- [hiper-] — above, over (hyperostósis — hyperostosis);
- syn-, sym- [sin-, sim-] — together, jointly (synostósis — synostosis);
- my(o)- [mio-] — relating to muscles (myológia — myology);
- phys- [fiz-] — relating to growth in a specific location (diáphysis — diaphysis).
