The kanji 胎 is a phono-semantic compound. It is composed of two parts: ⚫︎ The semantic (meaning) component is 月 (getsu/tsuki), meaning "moon" or, in this context, “flesh” or "body." 月 also appears in other kanji related to the body such as 肝 (liver). ⚫︎ The phonetic (sound) component is 台 (dai), which provides the sound "tai". Therefore, the character suggests the idea of a developing life form within the womb, represented by the "flesh" component, and it is pronounced “tai” based on the sound of the character 台.
