Persian to Setswana: a mass-class prefix does not count containers of water
Separate the material from the unit being counted
The Texas Persian counting lesson distinguishes a material from an individual unit with yek dāne berenj, a single grain of rice. Its dó qāleb-e sābun example counts two bars of soap rather than two unspecified amounts of a substance. A Setswana translation needs to preserve the grain or bar relationship whenever that unit is part of the instruction.
This is particularly consequential in a recipe or supply request. A request for a material, a measured portion and several packaged units can refer to the same substance while requiring different quantities. Choosing the target noun class does not by itself recover a missing measure. The unit expressed in the Persian phrase must remain identifiable in the target construction.
Setswana mass nouns can belong to a class associated with plurals
The SADiLaR Setswana grammar lists mêtsi, water, and mas(w)i, milk, among class-six collective nouns without an ordinary singular counterpart in the discussed group. Their class prefix is not an instruction to imagine several bottles. The noun can denote the substance while its grammatical class controls the agreement required around it.
Thus a Persian reference to water should not acquire several separate water containers simply because the chosen Setswana noun has class-six morphology. Conversely, an explicitly counted container phrase cannot lose its count merely because the contained material is a mass noun. Material reference and packaging reference answer different questions in the request.
The distinction also affects follow-up descriptions. Setswana agreement is organized by noun class, as the grammar explains, rather than by a direct imitation of the source word’s visible singular or plural shape. Rebuilding that agreement preserves target grammar without authorizing a change in how much material is requested.
Persian inflection is not a reliable target agreement instruction
The source counting lesson illustrates dah ketāb, ten books, with a noun lacking a plural suffix after the numeral. The ten individual items remain plural in meaning. This supplies another reason to recover the quantity from the whole Persian phrase instead of treating an unmarked noun as evidence that only one item is involved.
Applied to supplies, identify whether the source counts individual objects, portions or containers, and which noun names the material. A numeral attached to the container count must not become a count of distinct substances. A request for two bars of one soap is different from a request for two kinds of soap.
For Persian into Setswana, interpret the source measure before choosing target agreement. The target noun class can require grammatical marking even where Persian has no corresponding prefix; it cannot silently add a bottle, grain or other unit. Preserving that division keeps a material-only request distinct from a measured or packaged quantity while allowing each language to express its own noun structure.
