适度

• Pinyin: shì dù
• Hanzi breakdown: 适 = 辶 + 啇 (to fit, to suit — moving toward what is appropriate); 度 = 广 + 廿 + 又 (degree, measure — estimating spatial or temporal extent)

Do Say

• 营养学家指出，碳水化合物并非减肥的天敌，关键在于摄入总量的适度控制和食物来源的合理搭配，而非将其从饮食中完全排除。(Nutritionists point out that carbohydrates are not the enemy of weight loss; the key lies in moderate control of total intake and a reasonable combination of food sources, rather than eliminating them completely from one's diet.)
• 政府在宏观经济调控中须把握适度原则，刺激政策力度不足则难以有效提振需求，力度过猛则可能引发通货膨胀和资产泡沫等连锁风险。(In macroeconomic regulation, the government must grasp the principle of moderation: if stimulus policies lack sufficient force they will struggle to effectively stimulate demand, while if the force is excessive it may trigger chain risks such as inflation and asset bubbles.)

Don't Say

• 适度 when you simply mean 'a little' or 'somewhat' — use 稍微 (slightly) or 有点 (a bit); 适度 specifically implies calibrating to an optimal level that avoids both extremes, carrying a prescriptive connotation that is absent from simple degree adverbs
