Definition of "haĉek"

Ask to be that diver falling haĉek into this wave.

2002, Andrew Zawacki, By Reason of Breakings, poem iv: “Diacritics”, page 28

BTW, Esperanto uses a “breve” on the “u”, i.e. ŭ, not a haĉek.

My father always wrote Bětik with a little “v” called haĉek, above the “e”; Marušaks placed the haĉek above the “s”.
