Zakef katan

Zakef Katan ( literally 'upright small'; various romanizations), often referred to simply as "katan", is a cantillation mark commonly found in the Torah, Haftarah, and other books of the Hebrew Bible. The note is the anchor and final one of the Katon group, which also can include the Mapach, Pashta, Munach, or Yetiv. It is one of the most common cantillation marks. There is no limit to the number of times the Katan group can appear in a verse, and often, multiple Katan groups appear in succession. The most times in succession the group occurs is four.
The symbol for the Zakef katan is a colon (:). It is placed on the syllable of the word that is accented.
