Applicative Before Passive

The Applicative Before Passive pattern is highly frequent and fully productive in Swahili. It is formed by attaching the applicative suffix followed strictly by the passive suffix to the verb root. The literal breakdown is the verb root + applicative (-i- or -e-) + passive (-w-) + final vowel (-a), combining to form -iwa or -ewa (e.g., pik-a → pik-i-a → pik-i-w-a).

1. Morphology and Vowel Harmony

• The choice between -i- and -e- follows standard vowel harmony: roots containing a, i, u take -iwa (e.g., pika → pikiwa), while roots containing e, o take -ewa (e.g., leta → letewa).
• For Bantu verbs ending in double vowels, an -l- is inserted, resulting in -liwa or -lewa (e.g., nunua → nunuliwa).
• For Arabic loanwords, the applicative passive forms are typically identical to their standard passive forms (e.g., samehe → samehewa, jibu → jibiwa, sahau → sahauliwa).
• For monosyllabic verbs, the forms can also be irregular or identical to the standard passive. For example, the applicative passive of la (eat) is liwia (distinct from the standard passive liwa), but for nywa (drink), the applicative passive is nywewa, which is identical in form to its standard passive.

2. Syntactic Rules and Agreement
The most important rule is that the recipient, beneficiary, victim, or location MUST be the subject of the sentence. Consequently, the verb's subject prefix must change to agree with this new subject (e.g., if 'I' am the victim, the verb must start with ni-). To see this subject prefix change in action, compare an active applicative sentence with its passive equivalent: Aliniandikia barua (He wrote a letter to me) → Niliandikiwa barua (I was written a letter). Crucially, when converting an active applicative sentence to a passive one, the object prefix representing the beneficiary (such as the -ni- in aliniandikia) must be dropped in the passive sentence. The original object being acted upon (the theme) remains in the sentence as a secondary object. While the beneficiary's object prefix is dropped, the theme can still take an object prefix if it is highly definite or animate (e.g., Niliipewa - I was given it). You cannot make the theme the subject of an applicative-passive verb. For locative applicatives, the location becomes the subject (e.g., Kiti kimekaliwa - The chair has been sat upon).

3. Expressing the Agent and Adversative Nuance
If you want to state who performed the action, use the preposition na (by) followed by the agent, just like in a standard passive sentence (e.g., using a Passive Agent with na). While often called "benefactive," this pattern is equally used for negative events where someone is the victim of an action (malefactive). For example, niliibiwa simu na mwizi means "I had my phone stolen by a thief."

4. Homophony with Simple Passives
Because Bantu verbs ending in double vowels insert an -l- in their simple passive forms, the simple passive and the applicative passive often look identical (e.g., nunuliwa). This homophony also applies to many Arabic loanwords (e.g., samehewa) and some monosyllabic verbs (e.g., nywewa), where the standard passive and applicative passive share the exact same form. The difference is entirely syntactic: if the subject is the item acted upon, it's the simple passive. If the subject is the person receiving the item or action, it's the applicative passive. Learners must rely on syntax and context (such as a human subject prefix) to distinguish them.

Promotion Changes the Slot:
Juma alinipikia chakula (Juma cooked food for me) becomes Nilipikiwa chakula na Juma (I was cooked food by Juma). The beneficiary’s -ni- object marker is replaced by subject ni-; its person reference remains, but its grammatical position changes.
