The kanji 培 is a phono-semantic compound. The left side is the radical 土 (tsuchi), meaning "earth" or "soil," which provides the semantic component, indicating that the meaning is related to the earth or growing things. The right side is 咅, which provides the phonetic component, indicating the sound バイ (bai). Together, the character signifies the act of cultivating the earth, like nourishing plants, and hence, "to cultivate" or "to foster."
