vast
🌊🏜️ 广 = broad roof, 阔 = life 活 beyond the gate 门 — endlessly vast
Both characters reinforce width. 阔 splits into 门 (gate) and 活 (alive) — what stretches beyond the gate is open and boundless.
广 — shelter/roof radical 广 (yǎn)
广 originally depicted a building leaning against a cliff or hillside — a roof or shelter open on one side. It serves as the 'shelter' radical (yǎn) in many characters related to buildings (店, 庭, 库). In simplified Chinese, 广 was also adopted as the simplified form of 廣 ('wide, broad').
阔 — door 門 + 活 huó (phonetic)
A semantic-phonetic compound: 門 ('door/gate') gives the meaning of a wide opening, while 活 supplies the sound. Originally suggesting a broad gateway, it came to mean 'wide, vast, spacious,' as in 广阔 or 阔气 ('extravagant').
