The kanji 延 is a phono-semantic compound (形声文字). The left side is a radical called 廴 which represents "to advance" or "to walk". The right side is a phonetic component 㞏 (also read as エン or en) which contributes to the sound and hints at the meaning of stretching out. The combination of these components suggests the idea of something extending or stretching forward.
