Learn Arabic (Modern Standard): لم تبق السائحات في المنتجع. - The female tourists did not stay in the resort.

In Arabic, when the verb comes before an explicit subject (Verb-Subject-Object order), the verb is always singular. It only matches the subject in gender (feminine), which is why it starts with a taa instead of a yaa.

تبق looks like it is missing a letter. What happened to the end of the verb?

The verb is بقي (to stay), and its normal present tense is تبقى. Because it is preceded by the negative particle لم, the verb takes the jussive mood. For verbs ending in a weak letter, the jussive is formed by completely dropping that final weak letter.

Since the verb is a present tense form, why is the English translation in the past tense?

The particle لم is used to negate the past tense. Even though it is always followed by a present tense verb form, the meaning of the phrase is shifted entirely to the past.

How do you pronounce the end of تبق in this sentence?

It is pronounced with a short a sound (a fatha) on the final letter. When the weak alif at the end of تبقى is dropped due to لم, it leaves behind the short vowel that matches it. It connects to the next word as tabqa s-sā'iḥāt.
