# Omar (name)

Omar/Umar/Omer is a masculine given name that has different origins in Arabic, Hebrew, and German.
Umar or Omar is a common name (Arabic: عمر) in Arabic-speaking and Muslim populations in general. Omar is represented in Islamic traditions, meaning 'flourishing, long-lived'. The name dates back to the emergence and military success of Islam, which were partly due to the second caliph Umar ibn al-Khattab (also spelled Omar, r. 634–644).
There was also a biblical figure by the name of Omer (Hebrew: אוֹמָר) in the Hebrew Bible, meaning 'eloquent' or 'gifted speaker'. Another similar Hebrew name is Omer (Hebrew: עומר), derived from 'sheaf' or 'bundle of grain'.
The name Ómar also became popular as a man's name in Iceland, and to a much lesser extent in Nordic countries. The name can also be a variant of Ottomar or Othmar, a Germanic name consisting of elements *aud, meaning 'wealthy', and *mari, meaning 'fame'.
The name Omaar (أومار) is a Somali name, not a variant of Omar/Umar. It comes from the Somali word Oomaar which means 'hot steam from boiling pot'.
