As I often do while I wait for programs to compile, I was browsing Wikipedia one day when I came across the page for Venerable Thích Nhất Hạnh. I was surprised to see my query for “Thich Nhat Hanh” redirected to “Nhat Hanh,” and when I read further, I was disappointed by the explanation given:
Commonly referred to as Thich Nhat Hanh (Vietnamese: Thích Nhất Hạnh), the title Thích is used by all Vietnamese monks and nuns, meaning that they are part of the Shakya (Shakyamuni Buddha) clan.
Almost right, but not quite. The Wikipedia article unfaithfully refences the Order of Interbeing, which actually informs us that Thích is a name, not a title:
Thích (釋) is Vietnamese for Sakya, which is the Buddha’s family name. Every monastic member in the Vietnamese Buddhist tradition has a name which begins with Thích.
