ku- (mahali)

The ku- general locative is one of three locative classes in Swahili (Class 17). It specifically refers to an indefinite, broad area or a general direction (toward or from). The word mahali (place) can take agreement for any of the three locative classes, but it takes ku- specifically when referring to a general or indefinite area. It shares its agreement markers with the Infinitive Class 15.

What it attaches to:

• Verbs and Copulas: As a subject prefix, it forms existential statements like kuna (there is/are) and hakuna (there is/are not). As a locative suffix, it appears as -ko to show location (e.g., niko 'I am around here', yuko 'he/she is around there').
• Adjectives: e.g., kuzuri (a nice general place).
• Possessives: Before a vowel, ku- changes to kw-. For example, ku- + -angu becomes kwangu (my place/around my home).
• Demonstratives: It forms location words like huku (around here), huko (around there), and kule (over there).
• Relatives: It uses the relative marker -ko- or ambako (where/around which).

How it differs from other locatives:
While pa- definite locative refers to a specific spot (right at/on) and mu- interior locative refers to an enclosed space (inside), ku- is for a broad area. For example, hapa means 'right here', but huku means 'around here'.

Object Infix Ambiguity:
The Class 17 object infix -ku- is identical to the Second-Person Object -ku- ('you'). Because a word like ninakujua is almost always interpreted as 'I know you', speakers often prefer to use the Class 16 marker (ninapajua 'I know the place') or the -ko suffix to avoid confusion when referring to places.

Important Notes:
ku- is an agreement marker, not a standalone preposition. However, it combines with the -a associative to form the highly common multipurpose preposition kwa (to, from, by, for). When a noun takes the -ni locative suffix (like shuleni) and implies a general area, all following modifiers must agree with ku-, not the noun's original class. Furthermore, the -ni suffix cannot be attached to people or animals. To express location at, to, or from a person, you must use kwa (e.g., kwa daktari 'at the doctor's', kwa Juma 'at Juma's').
