拟定 (nǐ dìng) means to draw up or formulate plans, documents, or policies through careful deliberation. It is more formal and thorough than 起草 (qǐ cǎo 'to draft'), which emphasizes the initial writing, and overlaps with 制定/制订 (zhì dìng) but is less about establishing official rules and more about working out details. The single character 拟 (nǐ) is a concise, literary equivalent often used in formal contexts.
