The Semitic root B-R-K has the original meaning of "to kneel down", with a secondary meaning "to bless".
In Islamic mysticism, Barakah (Arabic: بركة ) is a concept of spiritual presence or revelation. The cognate Hebrew term is Berakhah (בְּרָכָה) "benediction, blessing".
Baruch (Hebrew: בָּרוּךְ, Modern Barukh, Tiberian Bārûḵ; "blessed") is a Biblical Hebrew given name, most notably the name of Baruch ben Neriah, aide to the prophet Jeremiah.
The Arabic masculine given name Mubarak is the Arabic stem III passive participle, mubārak ( مبارك), meaning "blessed (one)".
The given name Barack of US president Barack Obama is derived from the same root. However, Bārak بارك is not a given name in Standard Arabic. The Arabic given name derived from the root B-R-K is Mubarak ( مبارك "blessed (one)"). However, it appears that the variant Bārak has a tradition as a masculine given name in Islamic parts of Sub-Saharan Africa.
