Block letters (known as printscript, manuscript, print writing, printing or ball and stick in academics) are a sans-serif (or "gothic") style of writing Latin script in which the letters are individual glyphs, with no joining.
Elementary education in English-speaking countries typically introduces children to the literacy of handwriting using a method of block letters (commonly referred to as manuscript by educators), which may later advance to cursive (joined) penmanship. The policy of teaching cursive in American elementary schools has varied over time, from strict endorsement such as the Palmer method in the early 20th century, to removal by Common Core in 2010, to being reinstated.[1]
On official forms, one is often asked to "please print". This is because cursive handwriting is harder to read, and the glyphs are joined so they do not fit neatly into separate boxes.
