Nicknames, from the old word ekename, meaning
additional name, are known in all cultures and have
been used for hundreds of years. At the end of the
first millennium, they were in common use by the
Vikings. Many of them were simply descriptive: Ketil
Flatnose, Hallgard Longlegs... . Among the
Turkanas of Kenya it is customary to give
descriptive names for a very good reason. The
Turkanas are a nomadic people, keeping sheep,
goats and camels. It is therefore useful for them to
be able to recognise people from a long distance
away. Hence nicknames such as "Ichang ichang",
meaning "crab", to identify someone who takes
quick little steps and "hiproll" for a large woman with
a swaying walk are common in everyday use.
