大 = big + 约 (yuē) = appointment/agreement → 'big agreement' = approximately
约 means to make a pact or set a rough arrangement, so 大约 literally pairs 'big' with 'agreed estimate' — a loose, ballpark figure. Use it for 'about, roughly, probably' with numbers, times, or guesses.
大 — pictograph of a person with arms outstretched
大 is a pictograph showing a person standing with arms and legs spread wide. The outstretched arms suggest 'big' or 'great', extending from the literal image of a large stance to abstract meanings like important or grand. It is one of the oldest characters, found on oracle bones.
约 — silk radical 糹/纟 + ladle 勺
约 combines the silk radical 糹 with 勺 (ladle), which provides the sound. Originally it referred to binding or tying with silk cords, from which came the meanings 'to bind by agreement,' hence 'pact, appointment,' and later 'approximately' (a loose, tied-up estimate).
