Embedded yes/no questions (ว่า...ไหม / หรือเปล่า)

Embedding Yes/No Questions with ว่า

When you want to say "whether" or "if" something is the case—like asking a clerk whether an item is in stock—you embed a yes/no question into your sentence.

To do this, use the linking word ว่า followed by the question clause ending with ไหม or หรือเปล่า.

Structure: [Main Clause] + ว่า + [Subject + Verb + (Object)] + ไหม / หรือเปล่า

Expressing Uncertainty and Wondering

This structure is extremely common when expressing uncertainty, curiosity, or when verifying information. The main clause will often contain verbs like "to not be sure" (ไม่แน่ใจ), "to wonder" (สงสัย), or "to check" (เช็ก / ตรวจสอบ).

Applying to Shopping Scenarios

You can use embedded questions to navigate various customer service situations, such as asking about discounts, claiming defective products, or checking on promotional free gifts.
