Questions & Answers about Tā shuō zhè gè ānpái hǎo, kěshì tā bù tóngyì, xiǎng zìjǐ zài ānpái yíxià.

Why is 个 used in 这个安排? Why not just 这安排?

In Mandarin, demonstratives like 这/那 must be followed by a measure word (classifier) before a noun. 个 (gè) is the default, general-purpose measure word, and it works with abstract nouns like 安排 (arrangement). So 这个安排 is the natural form.

• Alternatives with a more specific nuance are possible: 这项安排 (xiàng, for items/projects), 这次安排 (this time’s arrangement), 这份安排 (a document/plan as a “copy”).
• In fluent speech, 个 in 这个 is often pronounced with a neutral tone: zhège (also commonly zhèi ge in northern speech).

Is 安排 a noun or a verb here? It appears twice—what’s going on?

It’s both. 安排 (ānpái) can be a noun or a verb.

• In 这个安排, it’s a noun: “this arrangement.”
• In 安排一下, it’s a verb: “to arrange (a bit).” Also note the different pattern 安排好, where 好 is a result complement meaning “arrange well/finish arranging,” e.g., 把行程安排好 (get the itinerary arranged properly). In the sentence you’re asking about, 这个安排好 means “this arrangement is good,” not the verb-complement pattern.

Why is 好 used without 很 in 他说这个安排好? I was taught adjectives need 很 when used as predicates.
