KUWA: The Verb "To Be"
The verb "to be" is expressed with the monosyllabic verb kuwa. In the present tense, however, kuwa is not used nowadays (except in a very few isolated expressions); instead, "to be" is expressed in a non-verbal way for "is/are."
The most-used way of expressing "is/are" is by NI for all persons and noun classes. However, another form, the subject prefix standing alone, is preferred usage in some instances. In Class 1, the old prefix YU is used. The negative is always expressed with SI in the present. (Although NI is the preferred form in most normal usage, it is possible to hear kuwa used in these circumstances: (a) With HU tense: Huwa safi siku zote. It is always clean.; (b) In the negative: Hawi tayari. She is not ready. The non-standard negative form is used especially with the first person plural - compare these two equivalent alternatives to see why: hatuwi tayari
or sisi si tayari.)
|Mti ni mrefu or Mti u mrefu||Mti si mrefu|
|The tree is tall||The tree is not tall|
|Shati ni chafu or Shati li chafu||Shati si chafu|
|The shirt is dirty||The shirt is not dirty|
|Mtoto ni mdogo or Mtoto yu mdogo||Mtoto si mdogo|
|The child is small||The child is not small|

Fungu li kamili. The bunch is complete.
Nguo zi safi. The clothes are clean.
Tu wagonjwa. We are ill.
Wa wazima. They are well.
Kaka yu macho. (Our) brother is awake.
Although grammarians of some decades ago claimed that the subject prefix was the only alternative in this case, it must be noted that NI is frequently used by Swahili speakers in daily speech.
Ni mwalimu. I am a teacher.
U mkulima? Are you a farmer?
U nani? Who are you?
Tu walimu. We are teachers.
M wakulima? Are you farmers?
M nani? Who are you?
Obviously, these forms are more economical than saying, e.g., Wewe ni nani?
Sisi tayari. We (are) ready.
Yeye mgonjwa. She (is) ill.
Hiki changu. This one (e.g. knife) (is) mine.
Nyumba yako nzuri. Your house (is) nice.
In tenses other than the simple present, kuwa is a part of the verb construction like any other monosyllabic verb. NOtice the constructions in which the KU infinitive is retained.

Si tayari. She is not ready.

Notice that in some tenses kuwa means "become":

Akawa mrefu. (and) she became tall.
In rare cases, kuwa may be used with the NA tense:
Jua linakuwa kali. The sun is (in the process of becoming) hot.
Jua ni kali. The sun is hot.
Kuwa forms the subjunctive construction exactly like any other monosyllabic verb:

Fimbo isiwe ndefu mno. The stick should not be too long.
Udongo uwe laini. The soil should be soft.

"To be" with the relative particle differs only in the present tense from other verb constructions with the relative.
An old verb for "to be," LI, is used when making a relative construction in the present tense.
This verb must not be confused with the LI tense.
The construction is identical to the General Relative verb form (paragraph 68), i.e., Subject prefix + verb stem + relative.
