hiatus [hy‐ay‐tŭs], (i) a break in pronunciation between two adjacent vowels, either within a word (forming two distinct syllables, as in doing, rather than a diphthong as in joint) or between the end of one word and the beginning of the next (e.g. the expense rather than the elision of th'expense);

(ii) any gap or omission in a sentence, verse, or logical argument. See also diaeresis, ellipsis, lacuna.

hiātus (‘gap’), in Greek and Latin poetry, a break in a line when a vowel at the end of one word is not elided before a vowel at the beginning of the next, as it would be by normal scansion (see ELISION). If the earlier vowel is long it may retain its length or be shortened (for an explanation of ‘long’ and ‘short’ in metric see METRE, GREEK 1). Hiatus is common in Greek epic verse (see DIGAMMA), rare in Latin epic.

Pl. hiatus [L.] an aperture, gap, cleft or opening.

• esophageal h. hernia — see hiatal hernia.
• esophageal h., h. esophageus — the opening in the diaphragm for the passage of the esophagus and the vagus nerves.
• vena caval h. — the opening in the diaphragm for the passage of the caudal vena cava; properly called foramen venae cavae.
