The kanji 誕 is a phono-semantic compound (形声文字). The left side is a radical called 言 (げん - gen), meaning "speech" or "words," and the right side is 延 (えん - en), which means "to extend" or "to lengthen." The original meaning relates to announcing the birth of a child. The "言" component suggests that the birth is being announced or spoken of, while the "延" component might imply an extension of life or time as a consequence.
