Learn Italian: Non abbiamo ancora pagato la caparra. - We haven't paid the deposit yet.

This is an important vocabulary distinction at this level. A caparra is a binding, non-refundable deposit or earnest money—if you back out of the deal, you usually lose it. An anticipo is simply an advance payment or installment toward a total price. A cauzione is a security deposit meant to cover potential damages (like when renting an apartment), which is typically refunded to you later.

Why is ancora placed between abbiamo and pagato instead of at the end of the sentence?

In English we usually put 'yet' at the end of the sentence, but in Italian compound tenses like the passato prossimo, short adverbs of time such as ancora (yet/still), già (already), and mai (never) are almost always placed between the auxiliary verb (abbiamo) and the past participle (pagato). Putting it at the end sounds unnatural unless you are placing a very heavy, dramatic emphasis on the word.

La caparra is a feminine noun, so shouldn't the past participle be pagata?
