What ⹝ means
It marks a word break or a hyphen kept in the word.
In medieval European manuscripts, it showed that a word continued on the next line. By the Elizabethan period in England, the single form had become standard. A Middle Scots example uses double ⸗ at the break and single ⹝ after the broken word.
