晤

Left sun radical (Kangxi #72) - pictograph of the sun, a square enclosure with a central dot or stroke. In 晤 the radical signals daylight, brightness - meetings traditionally took place in daylight, face-to-face under the sun. Same radical anchors time-and-light chars: 明 (bright), 晚 (evening), 时 (time), 春 (spring).

Right 吾 supplies the sound (wú to wù, only tone shifts) and a fitting semantic flavour: 吾 is the classical first-person pronoun. A meeting between 'I' and 'thou' under daylight is exactly what 晤 names. Same phonetic in 悟 (awaken, mental meeting with truth), 梧 (paulownia), 语 (speech). 会晤 'meet' is the everyday compound.
