1.
stroke count (of a kanji or character)
The number of brush strokes needed to write a kanji character. Used in kanji dictionaries as one method of looking up characters, and also considered significant in fortune-telling based on the stroke count of one's name.
Usage
Stroke count is one of the three main methods for looking up kanji in a traditional dictionary, alongside radicals (部首) and readings. When you know neither the reading nor the radical of a kanji, you can count its strokes and search by 画数.
Cultural note
姓名判断 (name fortune-telling) uses the 画数 of a person's name to predict luck and compatibility. Many Japanese parents consider stroke counts when choosing names for their children.
