Ezért azt mondjuk, hogy kép | es | ség | ei | vel, illetve hogy ad | ós | ság | ai | val. Így nyilván mindenki ráismer erre a harmóniára.Now, the suffixes and derivational affixes generally have two forms, so that a low-vowel word can take a low-vowel suffix and a high-vowel word can take a high-vowel suffix. This is why we say "kép | es | ség | ei | vel" [with his/her abilities] and "ad | ós | ság | ai | val" [with his/her debts]. Thus, it is clear that everyone recognizes this harmony. For IPA use, the symbol may be made heavy to distinguish it from the dental click ⟨ǀ⟩.
* (IPA, boldface) Marks a minor prosodic break, anything from a metrical foot to the end of a continuing prosodic unit, depending on context.
    Coordinate term: ‖

** 2003 January 21, Jugoslav Dujic, “Re: Using common DLL routines...”, in comp.os.ms-windows.programmer.win32‎ (Usenet; in English):| Thanks, Barry. I was able to achieve run time linking by using your example as | a model, although, 1) I don't entirely understand the use of typedef, etc., | and, 1) From the viewpoint of just occasional user of C(++): I think that syntax of pointers-to-functions is just plain ugly, tough to remember and tough to comprehend.
* (Internet slang) In a title, separates related but distinct pieces of information.
