How to say "hiatus" in Japanese

• 裂孔れっこう
  nounThe anatomical sense: a slit-like opening in a body structure, as in the esophageal hiatus. Not used for a break in activity; outside medical contexts it is seldom the word you want.
• 母音接続ぼいんせつぞく
  nounThe linguistics sense: two vowels meeting directly across a syllable or word boundary with no consonant between them. A technical phonology term, not a word for a pause or gap in activity.
• 活動休止かつどうきゅうし
  nounA break or pause in work or activity, especially in a creative field; it suggests a temporary stop rather than a permanent end. The natural choice for a band or artist going on hiatus.

English 'hiatus' covers unrelated senses: use 活動休止 for a break from work, especially in a creative field; 裂孔 for an anatomical opening such as the esophageal hiatus; 母音接続 for adjacent vowels in phonology.
