From Latin plānus (flat, level, plain). The 'flat' sense branches widely: plain (flat land; clear/obvious), plane (flat surface), plan (a flat layout/drawing), platform (flat form), plateau (flat highland), and platitude (flat remark). Explain originally meant 'to flatten out' — make clear by spreading flat.
