Pronunciation of consonants in Latin

Dual pronunciation: letters C and S

The letter C is one of the most important for the correct pronunciation of medical terms because it has a dual pronunciation: it can sound like a hard [k] or like [ts].

The letter is read as [k] in the following cases:

• Before the vowels a, o, u. For example, caput [kaput] — head (or head of a bone/organ).
• Before any other consonant sounds: cranium [cranium] — cranium, clavicula [clavicula] — clavicle, crista [crista] — crest.
• At the end of a word.

The letter is read as [ts] in only one position — before the sounds [e] and [i]. In writing, this is expressed by the vowels e, i, y, as well as the digraphs ae and oe. Examples of this pronunciation: cervicalis [cervicalis] — cervical, incisura [incisura] — notch, caecus [caecus] — blind, coccygeus [coccygeus] — coccygeal, coeliacus [coeliacus] — celiac.

The letter S also has two pronunciation options:

1. In most cases, it is pronounced as the voiceless [s]. This also includes the doubled ss. Examples: sulcus [sulcus] — sulcus, os sacrum [os sacrum] — sacrum (sacral bone), dorsum [dorsum] — back or dorsum, fossa [fossa] — fossa, processus [processus] — process.
2. The letter becomes voiced and is read as [z] if it is located strictly between two vowels (vesica [vesica] — bladder). In addition, in words of Greek origin, it sounds like [z] when positioned between a vowel and the consonants m or n (chiasma [chiasma] — chiasm, platysma [platysma] — platysma).

Features of reading letters H, K, and L

The letter H represents a specific breathy sound. It is read like the Ukrainian [h] or German h. Examples: homo [homo] — human, hiatus [hiatus] — hiatus or cleft, humerus [humerus] — humerus, haema [haema] — blood.

The letter K is very rare in medical Latin. It is used almost exclusively in terms of Greek origin when there is a need to preserve the hard [k] sound before the sounds [e] or [i] (since a regular C in such a position would be read as [ts]). Examples: kyphosis [kyphosis] — kyphosis, kinetocytus [kinetocytus] — kinetocyte (motile cell). The only important exception is the word Kalium [kalium] — potassium, which is of Arabic origin.

As for the letter L, the main rule is that it is always read softly, regardless of the following vowels or consonants. Examples: labium [labium] — lip, lumbalis [lumbalis] — lumbar, pelvicus [pelvicus] — pelvic.

Specific consonants: X and Z

The letter X is interesting because it represents two sounds at once — [ks]. This rule applies in all positions. For example: radix [radix] — root, extremitas [extremitas] — extremity.

The letter Z is found only in terms of Greek origin. In Ancient Greek, it was pronounced as [dz], but in modern Latin, it is read simply as [z]. Characteristic examples: zygomaticus [zygomaticus] — zygomatic, trapezius [trapezius] — trapezoid.

For convenience, you can use a small comparative sound chart:

• The letters c and k represent the [k] sound;
• The letter combination qu represents the [kw] sounds;
• The letter x represents the [ks] sounds.
