Questions & Answers about ปริมาณ รถยนต์ บน ถนน พรุ่งนี้ คง ลด ลง ครับ
Why does this sentence use คง instead of คงจะ?
Both are perfectly fine to use. คงจะ means probably will, and dropping the จะ to just say คง is very common in everyday speech. It still carries the exact same speculative meaning when placed right before the verb ลดลง.
Why do we need the word ลง after ลด? Doesn't ลด already mean decrease?
Yes, ลด means to reduce or decrease. Adding the directional word ลง (down) emphasizes the downward trend or the final result of the decrease. It is extremely common in Thai to pair verbs of change with a direction, similar to saying go down in English.
The time word พรุ่งนี้ is right in the middle of the sentence. Could it go somewhere else?
Absolutely. Time words in Thai are very flexible. You can place พรุ่งนี้ at the very beginning of the sentence to emphasize the time, or at the very end. Putting it right after the main subject phrase (ปริมาณรถยนต์บนถนน) is just one natural way to frame the context before stating what will happen.
Could I use จำนวน instead of ปริมาณ for the amount of cars?
You could, but ปริมาณ sounds more natural when talking about traffic. จำนวน specifically means number and is used for things you are actively counting one by one. ปริมาณ means quantity or volume and is perfect for a bulk concept like the overall volume of cars on a road.
