The kanji 講 is a phono-semantic compound (形声文字, けいせいもじ). It combines two parts: The left side is 言（げん）, which means "word" or "speech," and acts as the semantic component, indicating the meaning relates to speaking or words. The right side is 工（こう）, which acts as the phonetic component, indicating the sound こう（kō). The entire kanji depicts the act of speaking or explaining with words, hence "to lecture."
