Uintjie means: A South African term for the small, edible underground bulbs of various indigenous plants - typically from the iris family. In Afrikaans, uintjie literally means 'little onion,' and these starchy,. It is mainly South African English and may not be understood outside that context. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. This is a food-related word and harmless in itself.
