Question 1

Why is wawili used here instead of the more familiar mbili?

Accepted Answer

wawili is the form of “two” that agrees with noun class 2 (human plurals). polisi (police officers) belongs to class 2, so you attach the class 2 prefix wa- to mbili:  
• wa + mbili → wawili

Question 2

Can you break down the verb wanasimamia into its parts?

Accepted Answer

Yes. wanasimamia =  
• wa- (subject prefix for 3rd person plural, class 2 “they”)  
• na- (present‐tense marker)  
• simamia (verb root “to oversee/supervise”)  
Altogether it means “they are supervising.”

Question 3

What does foleni ya tiketi mean, and why is ya used?

Accepted Answer

foleni ya tiketi literally means “queue of tickets” – i.e. “ticket line.” In Swahili, ya links a noun to its possessor (genitive) for class 9/10 nouns. Here:  
• foleni = “queue/line” (class 9/10)  
• ya = genitive marker for class 9/10  
• tiketi = “ticket” (loanword, also treated as class 9/10)

Question 4

Why is ndani ya stesheni used for “inside the station”? Can you use katika instead?

Accepted Answer

Both can express “in,” but:  
• katika stesheni = “in the station” (general location)  
• ndani ya stesheni = “inside the station” (emphasises interior)  
Note: ndani behaves like a noun in class 9/10, so it also takes the genitive ya.

Question 5

Why does the verb still have a subject prefix when the subject Polisi wawili is already stated?

Accepted Answer

In Swahili you normally include a subject prefix on the verb even if you mention the noun subject. The prefix shows agreement (person, number, class) and tense. Omitting it in a simple declarative would be ungrammatical.

Question 6

How would you say “A single police officer supervises the ticket line inside the station”?

Accepted Answer

Replace wawili with mmoja (“one” for class 1) and use the class 1 prefix a-:  
Polisi mmoja anasimamia foleni ya tiketi ndani ya stesheni.  
Breakdown:  
• mmoja = “one” (class 1)  
• a- = 3rd person singular prefix (class 1)  
• na- = present‐tense marker

Question 7

Why are there no words for “a” or “the” in this sentence?

Accepted Answer

Swahili does not have articles equivalent to “a” or “the.” Definiteness or indefiniteness is inferred from context or added with demonstratives (e.g. huyu, yule for “this/that”).

Question 8

What is the typical word order in this sentence?

Accepted Answer

It follows the common S-V-O-(Adverbial) pattern:  
• S = Polisi wawili (Subject)  
• V = wanasimamia (Verb)  
• O = foleni ya tiketi (Object)  
• Adverbial (place) = ndani ya stesheni
