Consonants (
ongwaqa) are composed of one or more graphemes. At least one of these indicates the place and manner of articulation. If more than one such consonant grapheme is superimposed, this represents a co-articulation, e.g. an
affricate (formed of superimposed stop and fricative graphemes), or an
onset cluster. Other overlaid dots and strokes indicate articulatory mode, whether that be
voiced,
prenasalised,
implosive,
ejective,
modal voice, or a combination thereof. The position of the consonant graphemes largely corresponds to the
place of articulation: •
Labials and
nasals are positioned outside the triangle, at the apex. •
Alveolars are across the middle of the triangle from side to side. •
Dentals are two lines across the triangle from side to side, parallel to each other. •
Velars and
palatals are at the base. •
Laterals are outside the triangle on one side. The shape of the consonant grapheme corresponds to the
manner of articulation: •
Fricatives are indicated by curved lines; with the
retroflex/whistled and
postalveolar fricatives being loops. •
Plosives are indicated by straight lines in the same position as their fricative counterparts. • A plosive is written together with a fricative to write an
affricate. The post-alveolar and retroflex affricates are ligatures, with the plosive line integrated into the fricative loops. •
Approximants and
trills are represented with parallel lines or a line with a right angle in it. •
Nasals, including prenasalization of plosives and affricates, are represented as circles at the apex of the triangle. Lines inside the circles distinguish the nasals from each other, unless a plosive is present, in which case the distinction is not necessary. •
Clicks are a bottomless hourglass-like shapes. • Onset clusters such as
tw are similar to affricates: both consonants are placed in the triangle, though some spacial adjustment may be necessary. • Syllabic laterals and trills are represented with duplication of the ordinary lateral and trill graphemes. • Syllabic nasals,
amaQanda, are unique in that they are circles rather than triangles that occupy the entire
iBheqe space. They follow the same principles as their onset-nasal counterparts. These graphemes can combine with each other in an order in accordance with the
phonotactics of siNtu languages, and they also can combine with the articulatory mode graphemes. While normally the voicing line (described in the next section) goes right across the
amaBheqe, in the case of the post-alveolar and retroflex sibilants and affricates (that is, ), the line goes up to the loop, not passing through it, staying on the bottom half for post-alveolars and on the top half for retroflexes. These could be considered ligatures; even so, abbreviation is possible in handwriting, going from the loop part straight to the
uphimbo. ==Articulatory mode==
