- The wordA minute quantity measured as a fraction of a drop.
- A place to readThe historical definition below, 1650 dictionary, unnumbered definition page 28; facsimile PDF page 356.
Historical definition
Karena is the twentieth part of a drop.
Meaning
The entry defines a relation of one part to twenty. Its unit is a drop, whose material size the dictionary does not standardise. The precision of the fraction must therefore be distinguished from the absence of a fixed volume for its base unit.

In this edition
The fraction is retained without conversion into a modern volume. Such a conversion would require information about the liquid and the way drops were produced which this definition does not supply.
