What does quadrat mean?
In modern English, quadrat is a specialist printing and typography term for a small metal block inserted into a page of type to create space. Such blocks came in standard widths and could be combined to separate words, indent lines, align columns, or adjust the overall fit of a page. Because the object itself is a piece of type used for spacing rather than for printing letters, the term names the material and the typographic function together. The word is uncommon in general conversation but familiar to printers, publishers, and people working with page layout. It is also occasionally understood more broadly as any blank type block or spacing piece. Though its ordinary spelling and pronunciation may suggest an unfamiliar kind of mathematical object, quadrat belongs securely to the practical vocabulary of printing: a “space” made of metal.
nounA quadrat is a small metal block used in typesetting to fill space between or around pieces of type. Such blocks could be combined to adjust spacing, indentation, alignment, and page layout.

Where does quadrat come from?
Quadrat came into English through French quadrat, from Medieval Latin quadratum, the neuter form of Latin quadratus, meaning “squared” or “square.” Its printing sense arose because the spacing blocks could be square or rectangular pieces of type. Related English words include quadratic, quadrature, quadrate, and square, all reflecting the Latin quadratus family.
