Quite true Stany. So what's your advice to those who interchange 'l' and 'r'?

advice for them is to make proper use of words as they are... no short cut

The effect of improper use of "r" or "l" could also be observed in either language be it Swahili, English to mention a few.

For your cited case, Swahili as an example:

Kula-Kura.

The incorrect use of "r" or "l" might result into the following ambiguous meaning:

Kula=Eat?
Kura=Vote?

The bottom line is:all languages would need one to adhere to its correct use.
