Questions & Answers about Si rahisi kusoma usiku.
What does the word si do in this sentence?
Si is the negative copula meaning “is not/are not.” So Si rahisi = “It is not easy.” The affirmative counterpart would be Ni rahisi = “It is easy.”
Why is it si, not sio or siyo?
All three are heard. Si is the concise, standard written form of the negative copula. Sio/Siyo are very common in speech (especially regionally, e.g., Kenya) and are widely understood. Here, Si rahisi … is the most neutral choice, but Sio/Siyo rahisi … won’t confuse anyone.
Where is the English “it” in “It’s not easy to study at night”?
Swahili doesn’t need a dummy subject like English “it.” The structure is simply predicate + infinitive:
- Si rahisi kusoma usiku. = “Not easy (to) study at night.” You can also front the infinitive: Kusoma usiku si rahisi.
What is the ku- in kusoma?
ku- marks the infinitive/verbal noun: kusoma = “to read/study” or “reading/studying.” Infinitives can act like nouns, so they can be subjects or complements: Ni rahisi kusoma = “It is easy to study.”
