Active Passive
-kata cut -katwa be cut
-ita call -itwa be called
-pata get -patwa be got
-penda love, like -pendwa be loved
-panda plant -pandwa be planted
-lima cultivate -limwa be cultivated
-tumia use -tumiwa be used
Verbs ending in two vowels (especially those ending in -aa, -ua, or
-oa) are often an exception to the rule of passive formation, since
they insert -liw- or -lew-, rather than simply -w-, before the final
vowel, e.g. -nunua ‘buy’, -nunuliwa ‘be bought’:
Mwanafunzi alinunua vitambaa.
The student bought the cloth.
Vitambaa vilinunuliwa na mwanafunzi.
The cloth was bought by the student.
The choice of the vowel (-lew- with e, or -liw- with i) depends on
the vowel of the base form, and is governed by the rules of vowel
harmony: -lew- is chosen for verbs whose stem vowel is either e
or o, while -liw- is chosen for all others, that is those whose stem
vowel is a, i, or u. We sometimes write ‘I’ to mean ‘either e or i’,
so that the long passive extension can be described as -lIw- as
shorthand for ‘either -liw- or -lew-’.
Another example of the passive can be seen in Unit 3 (Dialogue
1) in the different expressions used by men and women to say that
they are married:
-oa marry (active – used when referring to a man)
-olewa be married (passive
– used when referring to a
woman)
Another class of exceptional verbs are those whose final vowel is
not -a (these are verbs of Arabic origin ending in -i, -u, or -e),
which take -iwa and -ewa instead of the final vowel:
-jibu ask -jibiwa be asked
-samehe forgive -samehewa be forgiven
Monosyllabic verbs also take either -iwa or -ewa:
-pa give -pewa be given
-la eat -liwa be eaten
-nywa drink -nywewa be drunk
