話し合う

The word 'hanashiau' is a compound verb formed from 'hanasu' (話す), meaning 'to speak' or 'to talk,' and 'au' (合う), meaning 'to fit,' 'to match,' or, in this context, indicating a reciprocal action. 'Hanasu' (話す) itself is an ancient Japanese word. Its kanji 話 is a phono-semantic compound where 舌 (shita, 'tongue') provides the sound and 言 (gen, 'word,' 'speech') provides the meaning. This graphically illustrates the act of speaking with one's tongue. 'Au' (合う) also has ancient roots, signifying a coming together or mutual action. When suffixed to a verb stem, it often conveys the idea of doing something to or with each other. For example, 'machiawaseu' (待ち合わせる) means 'to meet up' (from 'matsu' 待つ, 'to wait', and 'au' 合う). Therefore, 'hanashiau' literally translates to 'to speak mutually' or 'to talk together,' encapsulating the nuance of a reciprocal discussion aimed at understanding or agreement. This compound structure makes the meaning of collective deliberation very clear, distinguishing it from simply 'hanasu' (to speak) or 'soudansuru' (相談する, to consult), which might not imply the same level of mutual exchange or consensus-building.
