Be careful with the tone when pronouncing 折扣; it is pronounced with the second and fourth tones. This word is typically used in informal contexts, such as shopping or casual conversations about sales, and is often paired with verbs like '给' (gei, to give) or '有' (you, to have).

In Chinese culture, shopping festivals such as Singles' Day (双11) often feature significant 折扣s, reflecting the importance of sales events in consumer behavior and spending.

Learners often confuse 折扣 with 价格 (jià gé, price) by saying '我喜欢折扣' (I like the price), instead of '我喜欢折扣' (I like the discount). Ensure you use the correct context for discounts.
