Isaiah

Yahweh is salvation.

Isaiah is a masculine name with Hebrew roots, carried into English through the biblical prophet. Its meaning, ‘Yahweh is salvation’, gives it an explicitly religious starting point. Its sound can be surprisingly fluid beside that solemn association. The open vowels and soft ending give Isaiah a lyrical quality. In American English the stressed middle has the vowel of ‘say’; the British form instead has the vowel of ‘sigh’. Both belong to English usage, so choosing the sound matters as well as choosing the spelling.

Etymology: The English biblical form comes from Hebrew Yeshaʿyahu, combining salvation with the divine name.
