bouma shape
n.— «I didn’t really invent the term “bouma”: it’s adapted from the term “Bouma-shape” used by Saenger in his “Space between words”; he in turn claims to have taken it from the work of Taylor & Taylor (although I myself have yet to find any such term used by them), and is based on the Dutch psychologist Herman Bouma who formalized empirical research into word-shape-based reading. Professor Bouma himself had never heard of the term (a friend of mine asked him). The only things I can take credit for is making it convenient (a single lc word), and spreading it.» —“Bouma” by Hrant H. Papazian Typophile Forums Sept. 25, 2002. (source: Double-Tongued Dictionary)
