Just as the Sesotho sentence centres around the Sesotho noun

Sesotho nouns

Sesotho nouns signify concrete or abstract concepts in the language, but are distinct from the Sesotho pronouns.Bantu languages are often said to have sentences which are "centred around the noun" due to the striking nature of the noun concordance system...

, the noun is made to "concòrd" ("agree") with the verbs, pronouns, and qualificatives describing it by a set of Sesotho noun concords.

The noun concord system is the most striking feature of the Bantu language family

Bantu languages

The Bantu languages constitute a traditional sub-branch of the Niger–Congo languages. There are about 250 Bantu languages by the criterion of mutual intelligibility, though the distinction between language and dialect is often unclear, and Ethnologue counts 535 languages...

. The exact number of concord types differs from language to language, and traces of this system (and the noun class system) are even found in some Niger–Congo languages

Niger–Congo languages

The Niger–Congo languages constitute one of the world's major language families, and Africa's largest in terms of geographical area, number of speakers, and number of distinct languages. They may constitute the world's largest language family in terms of distinct languages, although this question...

 outside the narrow Bantu family.

Concord types

There are seven basic sets of concords. Each noun class has concords in each set, and the first and second persons have unique concords in some of the sets (the third person uses the class 1 and 2 concords). The exact number of concords differs from language to language, but all Bantu languages have at least the subjectival and objectival concords.

In form, the concords closely resemble the class prefixes, and it is not unreasonable to assume that originally the other parts of speech were made to agree with the noun by simply prefixing them with the noun's class prefix. Today, in Sesotho, the vowels and consonants of the prefixes have been modified slightly in largely predictable ways.

In addition to these seven concords, there are two further immutable concord-like prefixes used in certain situations with verbs.

Sesotho is a pro-drop language

Pro-drop language

A pro-drop language is a language in which certain classes of pronouns may be omitted when they are in some sense pragmatically inferable...

 in that in most situations separate words (such as absolute pronouns) do not need to be used with verbs to indicate the subject and object (they may be inferred from the subjectival and objectival concords).

Notes on the tables:

1. [N] means that nasalization will occur, with the syllabic nasal appearing only for monosyllabic stems. N means that the syllabic nasal will always appear.
2. "Class 1(a)" means class 1 and class 1a, while "class 2(a)" means class 2 and class 2a. Either group uses exactly the same concords, differing only in the class prefix and content.
3. All the locative classes (classes 16, 17, and 18) use the same concords, which resemble those of class 15.
4. When two forms of enumerative concords occur, the first one is the "strong" one, and the second is the "weak."

In the following discussion, weakening a prefix means removing the m nasal from the class 1, 3, and 6 prefixes, leaving only the vowel. The class 9 prefix is weakened to . In the examples, the noun is in bold, the concord is bold and underlined, and the word or clause which concords with the noun is underlined (nom. ... conc. + base).

• The pronominal concords are used in the formation of the absolute pronouns.
  
  In form they very roughly appear to be the weakened prefix followed by the open-mid back vowel . They all have a low tone.
  
  Doke & Mofokeng, using evidence from Setswana, claims that in fact the pronominal concords are derived from the absolute pronouns.

• The relative concords are used to concord with relatives and relative clauses.
  
  In form, for the noun classes, they appear to be the weakened prefixes coalesced with the close-mid front vowel . This coalescence has the effect of moving the close and near-close front vowels and to close-mid front , moving the near-close back vowel to the close-mid back , and alveolarizing the consonant to . The class 9 concord is and class 1(a) has an irregular concord (which appears as in non-standard speech) suggesting an inherent close-mid front vowel.
  
  Interestingly, this is one instance of the high toneme appearing as the extra-high allotone without immediately following another high tone (see Sesotho tonology
  Sesotho tonology
  Like almost all other Niger–Congo languages, Sesotho is a tonal language, spoken with two basic tones, high and low . The Sesotho grammatical tone system is rather complex and uses a large number of "sandhi" rules.However, the Sesotho system is by no means the most complicated, nor even one of...
  
  ). Most other instances of seemingly tonemic extra-high tones are found in ideophones, which have a tendency of not following the phonological laws of the language.
  
  The relative concords for the 1st. and 2nd. persons resemble the subjectival concords and are only rarely used, and only for relative clauses (never with relative stems). The 1st. and 2nd. persons usually use the class 1(a) and 2(a) concords instead.

• The adjectival concords are used with adjectival stems.
  
  In form they appear to be the relative concords followed by the class prefix. Class 1(a) has an irregular concord (but it appears as in non-standard speech). The classes have irregular concords instead of the expected }, though this is their form are in Setswana. The nasalization does not affect adjectives beginning with . The nasalization caused by the class 8 adjectival concord is probably due to false analogy with the class 10 forms (in isiXhosa, for example, the class 8 concord does not cause nasalization).
  
  Being formed from the relative concord followed by the class prefix, they therefore have tonal pattern [ ¯ _ ].
  
  The first and second persons use the class 1(a) and 2(a) adjectival concords.

• The enumerative concords are used with the enumerative stems.
  
  In form, the weak concords appear to simply be the weakened form of the prefix, while the strong concords are just the class prefixes. The weak concord for class 9 has the form .
  
  They have a low/null tone.
  
  

  You gave me the name of the head of the wrong department

• The possessive concords are used with possessives.
  
  In form they appear to be formed from the subjectival concord by addition of the vowel with various regular phonological side effects.
  
  They all have a high tone.

• The subjectival concords concord with the subject of a verb.
  
  
  They are placed near the beginning of the verbal complex, before any possible infixes verbal auxiliaries and the objectival concord, but after any pre-initial morphemes. In a multi-verbal conjugation they appear before every deficient verb (with the exception of contractions) as well as the main verb. The subjectival concord is needed even if the subject is explicitly stated.
  
  In form they appear to simply be the weakened prefix (class 9 [N] weakening to ).
  
  The forms given above are only for the positive indicative mood. In the indicative negative, the subjunctive, the potential, and the participial moods class 1(a) becomes . In the potential mood (using the infix in the positive) 1st. pers. sg. is N ( and ). In the past subjunctive an assimilated infix -a- affects all the concords, resulting in what is sometimes called the "auxiliary concord."

  The positive indicative concords are low (or alternatively, null) toned, and those for the noun classes are high toned. In the past subjunctive all the concords are low toned.

• The objectival concords concord with the object of a verb.
  
  They are placed right next to the main verb stem. In a multi-verbal conjugation they are used only with the main verb. Usually they do not appear on a verb if the object is explicitely stated (unlike subjectival concords, which have to appear in every predicative), but they can be used with the object to emphasise it and the action, or if the object appears before the verb (which also emphasises it).
  
  In form they resemble the subjectival concords, differing only in the 1st. pers. sg. and class 1(a). Before verb stems beginning with a the + combination contracts to due to the middle vowel being elided.
  
  If the following verb stem is of more than one syllable, they cause the following syllable (the stem's first syllable) to have a high tone and appear with a low tone. However, if the verb stem is only one syllable long then it is the concord itself which is pronounced with a high tone.

• The reflexive prefix is used to form reflexive verbs. It is not a concord in that it does not agree with any noun prefix, but it exhibits concord-like behaviour.
  
  It is simply the close vowel with the additional effect of nasalizing the verb to which it is attached. Thus its form is .
  
  In form and function it behaves like the objectival concord (therefore it cannot be used with the objectival concord), including the behaviour of raising the tone of the first syllable of the verb stem. However, unlike the objectival concord, it can also be used to form non-infinitive nouns from verbs.
  
  

  He is supposed to fetch it for himself (verb to fetch on behalf of)

  answer on behalf of ⇒ to answer for oneself ⇒ responsibility

  
  
  When used with causative verbs it often has the meaning of "pretend to be"

  die ⇒ cause to die (never used directly) ⇒ to feign death (lit. to cause oneself to die)

  sleep ⇒ cause to sleep ⇒ to pretend to be asleep (lit. to cause oneself to sleep)

• The indefinite concord is used in certain copulative constructions.
  
  It only exists as a subjectival concord and appears in form to be the subjectival (and "auxiliary") concord of class 9.

  It is only used as the subjectival concord for 3rd. persons and noun classes in the direct tense of the copulative employing the verbs , , and (including multi-verbal conjugations), when the copulative base is a noun or pronoun.
