consult with
詢 centers on seeking input through words: consulting with someone to get their opinion or advice.
詢 combines 言 (speech) with 旬, which likely contributes the sound and may suggest a cyclical or thorough quality to the consultation.
The left side is 言 (words), and the right side is 旬 (a ten-day period). Imagine a leader spending ten days asking for everyone's words before making a decision: that's consulting thoroughly.
For ジュン, picture consulting with a wise person in June: June -> ジュン, and their words guide you.
