allah
Synonym discussion
Sense: noun/1
All four words can refer to a single supreme being, but they carry different cultural and religious associations. "God" is the broadest English term and works in almost any context, religious or casual. "Allah" is the Arabic word for God; English speakers use it mainly when talking about Islam, although Arabic-speaking Christians and Jews also use it in their own worship. "The Almighty" is a formal, respectful title that avoids naming any specific tradition; it is common in literature and speeches. "Yahweh" is the Hebrew name found in Jewish scripture and academic discussion of the Old Testament. Compare: a news report might say "Muslims gathered to pray to Allah," while a Christian hymn might address "the Almighty," and a Bible scholar might write about "Yahweh."
Etymology
Allah comes from the Arabic word "Allāh," which most scholars believe was formed by joining the Arabic article "al" (meaning "the") with "ilāh" (meaning "god" or "deity"), giving the literal sense "the God." The word shares an ancient Semitic root with the Hebrew "Eloah" and "Elohim" and the Aramaic "Elah," all used for the divine. It entered English in the sixteenth century through European travel writing about Arabia and Islam.
