At a Glance

The word. A material identified through the older name rapes and two descriptive qualities.

In the book. The short gloss gives no further description, part, habitat or preparation.

A place to read. The historical definition below, 1650 dictionary, unnumbered definition page 37; facsimile PDF page 365.

Historical Definition

Perdetæ are small, yellow rapes.

Meaning

The definition’s useful details are smallness and yellow color. The older English name rapes is retained rather than silently assigned to one exact modern species or variety.

Use in the Book

The short gloss gives no further description, part, habitat or preparation. Those limits matter when a historical material name cannot be securely resolved from this witness alone.
