So my Swahili teacher has little to no linguistic knowledge. She also has little experience teaching foreign languages...or teaching at all.
We started to learn about noun classes in Swahili. Nouns are arranged in sets which usually have distinct singular and plural forms expressed by different prefixes attached to common stems. There are a total of.. five sets of nouns with singular/plural pairs, and six more noun class sets with no distinct plural forms. The classes are determined by what "kind" of nouns the stems consist of. For example, Class one/two, M-/WA-, consist of nouns related to people. Another class would consist of nouns related to plants, and so on...
We learned the noun class one/two, M-/WA-. The general rule is, to make the noun stem singular, you add M- in front of it. To make it plural, add WA-. For example, m-tu, wa-tu 'person, people.'
My teacher added, "but when the stem starts with a vowel, add MW- to make it singular, and W- to make it plural."For example, mw-alimu/w-alimu 'teacher, teachers.'
Then I looked at the list of nouns in this class and noticed that some of these vowel-initial nouns didn't follow the latter rule. Say, wa-afrika 'africans' or wa-ongo 'liars.' Why isn't it w-afrika or w-ongo? I asked her.
And she didn't have an answer. -__- According to her, these were just "exceptions" that you gotta suck up.
However as a linguistics student, I was convinced there had to be a reason why there were certain exceptions to the MW-/W- rule.
So, out of curiosity, I did some research at the library to find the "rules" to the exception. I found some books on Swahili from a linguist's point-of-view. And I think I have found the solution:
(*reference from Swahili Language Handbook, by Edgar C. Polome and Swahili Grammar and Syntax by Alfons Loogman)
1. M- always becomes MW- before a class 1 noun that starts with a vowel.
...However there is ONE exception: Mume 'husband.' It is not mwume. This is the only exception with the singular form.
2. With the [wa] (also [ma] and [pa]) nominal class-prefixes, contraction occurs before initial /a/, /e/, and /i/ of the following word-stem.
i.e., WA- becomes W- in front of noun stems that start with a, e, or i.
The first thing to note is that the contraction does NOT apply to ALL VOWELS. It does not apply to /u/ or /o/. Therefore we can now justify:
mwongo --> waongo 'liars'
mwoga --> waoga 'cowards'
mwuzaji --> wauzaji 'seller'
mume --> waume 'husbands'
Please take note of that... and now, here is the EXCEPTION. Even if the word stem starts with /a/, /e/, or /i/, you still use WA- (no contraction) when:
(a.) the word stem is borrowed from a non-Bantu language
This explains:
mwingereza --> waingereza 'Englishmen'; from Portuguese ingles
...and other words pertaining to nationality (like waafrika)
(b.) the word is a verbal root, stem, or theme
This explains:
mwimbaji --> waimbaji 'singers'; from the verbal root imba 'sing'
3. Mwizi and wezi
So why does mwizi become wEzi (thieves) with an /e/?
This is because of this particular morphophonemic process in the Swahili language:
/a/ + /i/ --> /e/
(linguists call this a "reciprocal assimilation")
So the plural of mwizi is technically supposed to be 'wizi' or even 'waizi' (*see explanation below), but instead it becomes wezi with an /e/. This is simply because when /a/ meets /i/ (wa-izi), it becomes an /e/ (wezi).
An additional note... In the case of wezi (from WA + izi), native speakers are apparently no longer conscious of the connection with the verbal stem iba 'steal.' Look at the "exception" rule 2b. Since iba is a verbal stem, the plural should technically be "waiba." But I guess it was lost over time.
Aaaand so that's how I saved my Swahili class. I hope my classmates (mostly athletes that are frustrated with the teacher's inconsistency) appreciate the time I spent on this. Unfortunately I don't think this will be the last time... At least I'm teaching myself something.

Polyester leggings with white floral details; grey. Made in Japan.
Please don't wear leggings with just a T-shirt and go to class. Please. Leggings are not pants. Wear leggings with a skirt or a dresss. And don't wear them with running shorts and Uggs, either.
Actually, don't ever wear Uggs. kthx.
