Proto-Celtic theonym *Φanon- "mother", Anu is an Irish goddess with uncertain functions and often conflated with other figures of Irish mythology and folklore, like Danu. In the Lebor Gabála Érenn, 'Anand' is given as an alternate name for Morrígu. While an Irish goddess, in parts of Britain a similar figure is referred to as 'Gentle Annie', in an effort to avoid offence, a tactic which is similar to referring to the fairies as “The Good People”.
Etymology uncertain, possibly derived from Sanskrit (see Anuradha). This was the name of a 17th century noblewoman and queen consort of Mongolia, known for leading troops to successfully rescue her husband from enemy forces.
