A single letter can host both consonant and vowel diacritics (the C_diac and V_diac groups in Table 2, respectively).
the string ָ ‫,בּ‬ pronounced /ba/, is composed of the letter ‫ב‬ (representing the consonants /b/ and /v/), a consonant diacritic ּ◌ (specifying the consonant /b/), and a vowel diacritic ָ◌ (representing the vowel /a/).
