A few factiods
In South Africa, monitors are often referred to as "leguaans" which is probably a corruption of the word "Iguana" - a family of spine-crested, vegetarian lizards to which they are not closely related. Similarly, the Australians sometimes refer to monitors as "goannas". Interestingly, the name "monitor" may also be a case of mistaken identity: common in Egypt, they became known by the general Arabic term for lizards, ouaran. Pronounced waran, this was apparently confused by German naturalists for warnen, which was interpreted as "warning lizards". This was then Latinized to Varanus (the genus). Monitor came from this and has given rise to some authors attempting to explain the name by the lizard's alleged habit of keeping a look out, or giving warning of the presence of crocodiles! (Which is a myth of course).
AND
If the word 'leguaans' is Afrikaans (although I believe that 'likkewaan' is a more common word in Afrikaans) it probably comes from the Dutch word 'leguaan'. In Dutch the name is correctly used for the species of the order Iguania. The Dutch name for monitors is 'varaan', from the name of the genus Varanus,

Surprisingly there are few published accounts of interactive behaviours such as ritual combat or courtship in Nile monitors. This can be attributed to the secretive behaviour of these huge lizards. Adults have been seen wrestling on the ground (presumed to be courtship by Clements (1968) but interpreted as ritual combat by Horn (1985). They have also been observed standing on their hind legs (Wearne 1962), but bipedal combat has not been observed to occur in this species. The Nile monitor makes great use of its tail for defence and the battered condition of these appendages in old specimens is attributed to its regular use as a club with which to deter aggressors.
A number of unusual behaviours have been noted amongst Nile monitors. A young monitor lizard that fell into a enclosure full of young (30cm) crocodiles
seized several of the crocodiles and turned them onto their backs before being removed. The crocodiles were estimated to weigh twice as much as the lizard (Pooley 1968).
According to Stevenson-Hamilton (1947) a monitor surrounded by four large lion cubs kept perfectly motionless apart from occasionally twitching its tail tip. The lion cubs watched closely, but appeared to interpret the movements as that of a snake and eventually wandered away.
The same author reports that an eagle which seized a Nile monitor was in turn seized by the thigh by the lizards, which steadfastly refused to let go. When found by a ranger the bird was in a state of utter exhaustion.
Buffrenil (1992) considered that, when fighting for its life, a Nile monitor was a more dangerous adversary than a crocodile of a similar size.
