Example Sentences

It should be borne in mind that j and ŭ are consonants, and do not, like the vowels, of themselves constitute a syllable.

The object of employing ss is to fix attention on the peculiar vowel-sound ŭ (see above).

Employed to mark the peculiarity of the final ŭ; hardly of greater power than ts.

Notice that the oblique cases of sūs have ŭ in the root syllable.
