Sesotho, or Southern Sotho, is the language of Lesotho and of South Africa's Free State, where it is the mother tongue of about seven in ten people. It is a separate language from Sepedi, the Northern Sotho of Limpopo, and the two carry their own pages here for a plain reason: a speaker of one follows only part of the other, so an interpreter belongs in the language actually spoken. Our office is in New York and the linguist travels to the hearing, the clinic or the interview. For in-person work we assign someone near you, and phone or video is usually available the same day.
Most people who need a Sesotho interpreter in the United States are older relatives, with the occasional witness or patient whose English is fine for the checkout line but not for a deposition or a diagnosis. The younger family arranging the appointment is usually fluent and rarely needs us for themselves.
Lesotho or the Free State? We ask before we assign. The vocabulary and the written forms differ across the border, enough that an interpreter placed on the wrong side of it starts filling gaps, and a courtroom is the worst place for that. It takes one question at intake. Because no state runs a court certification exam in Sesotho, a court works from a qualified interpreter rather than a certified one, and Sesotho is one of the rare languages a bench turns to us for when its own roster is empty. Prism works as a private agency and holds no court appointment.
Give us the county and the case type and we confirm what that court will accept before you commit to a date, because with no certification exam in the language the standard a bench applies varies from one state to the next. Most Sesotho court work reaches us by phone or video, since in-person linguists in this language are scarce and rarely close to the courthouse. We take instructions from courts, attorneys and law firms directly. Where a witness is giving evidence about a childhood lived entirely in Sesotho, we match the speaker's own side of the border so the account holds up under cross-examination.
A provider that takes federal funding has to supply a Sesotho patient with an interpreter at no charge, and most families never learn that this is a right. The bilingual daughter who normally translates for her mother is not the person for a cancer consultation or a consent form, however capable she is in daily life. Video works for a specialist review or a routine appointment. We send a person into the room for discharge planning, for a mental health assessment, and whenever an older patient plainly does better with someone present than with a screen.
Naturalization and adjustment interviews are the routine work, and the asylum interview is where the weight lands. The officer measures the applicant's exact words, the hesitations and the contradictions alike, so an interpreter who smooths an answer or supplies a silence hands over a different account than the one that was given. We brief every Sesotho interpreter to render what is said and no more, and we never put a bilingual relative in the interpreter's chair, whatever the goodwill.
Sesotho document work is heavier than most South African languages, because Lesotho, unlike South Africa, records much of its civil history in Sesotho itself.
Lesotho's civil registry in Maseru issues birth and death certificates, and its older records, church entries and chiefs' letters are frequently written in Sesotho, so a Lesotho file usually needs real translation rather than none. Registration has long been patchy, with fewer than half of young children recorded in recent years, so a Lesotho-born adult may hold a sworn affidavit of birth in place of a certificate, and we translate it as exactly what it is. The trap is the orthography: Lesotho keeps the older missionary spelling and South Africa uses its own, so a word like Modimo in the Free State appears as Molimo in Lesotho. A translator who silently harmonizes the two changes how a name reads against the passport, so we keep the spelling of the original and note the variant. A South African Sesotho speaker, by contrast, holds English Home Affairs certificates and needs us only for a statement or family document written in the language. The full document service is at certified translation.

Our only office is in New York, and our Sesotho interpreters work nationwide. For in-person work we assign someone based in or near the city. These are the areas where Sesotho work is concentrated; the full list of 288 cities is below it.
Prism Linguistics is rated 4.6 out of 5 across 67 client reviews for its interpreting and translation work in the United States. That is the company-wide figure; we do not publish a separate rating per language because there is no honest way to measure one. If a Sesotho assignment ever falls short, tell us and we put it right.
