Questions & Answers about wǒmen děi xiǎng yí gè bànfǎ jiějué zhè gè wèntí.
Here 得 means must, have to, or need to. So 我们得想一个办法 means we need to think of a way.
This is a different 得 from the very common grammar particle pronounced de or dé. Mandarin has several words written 得, so learners often have to tell them apart by context:
- děi = must / have to
- de = a grammatical particle, as in 跑得快
- dé = to get / obtain, in some words and expressions
In this sentence, it is clearly the modal verb děi.
This is because of a very common tone change rule for 一.
Normally, 一 is first tone (yī), but:
- before a fourth-tone syllable, it changes to second tone: yí
- before a non-fourth-tone syllable, it usually changes to fourth tone: yì
Here it comes before 个 gè, which is fourth tone, so 一 个 is pronounced yí gè.
