Duployan I Hook

It represents a word affix in some Duployan shorthand systems.

A prefix starts a word; a suffix ends it. The mark attaches to a letter, never another affix. “I hook” names its form, not a universal sound.

Duployan strokes join cursively, so neighboring letters and fonts can change the mark's shape or position in writing.

How did Duployan spread?

French shorthand grew into language-specific adaptations.

Émile Duployé published it in 1860 as shorthand for quickly recording spoken French. Adaptations also developed for English, German, Spanish, and Romanian. In British Columbia, Jean-Marie Le Jeune adapted its core to write Chinook Jargon and other Indigenous languages; Kamloops Wawa (1891–1923) used that branch without affix signs.
