i—GWALA, n. pl. ama.  (From the verb.)  Figuratively: a coward, lit. a foul or rusty character.
    u—GWALA, n. pl. izin.  (This is dialectic from an obsolete verb kwala, which radically coincides with kala, to cry out, or bring out a voice.  From that comes in-Kwali, fasan, so called from its cry or noise, and used in Zulu and Xosa.  The latter has also a verb, gwala, to whistle, and the noun ugwali, a flute or whistle, which is the same as this word.  But the noun i-Kwelo (derived from kwala), i.e.: whistling, both in Zulu and Xosa, places my etymology beyond all doubts, and ugwala is in tribal use besides.)
    A kind of flute.  In the Xosa a simple piece of reed, one or two feet long.  But in Natal a small bow, consisting of a stick and a string fastened at its two ends.  At the one end of the string a small piece of reed, from two to three inches long, is fastened, having a hole, to which the mouth is applied.  It gives a kind of tremulous sound.
    ubu—GWALA, n. sing. (From the verb gwala.)  Cowardice. (A Zulu-Kafir Dictionary, Döhne, 1857)
