Questions & Answers about Ayer compramos dos hachas afiladas.
Why is the adjective afiladas feminine when the singular is el hacha?
The word hacha (axe) is actually a feminine noun. It uses the masculine article el (or un) in the singular just to avoid the awkward double 'a' sound of la hacha. Because the noun itself is still feminine, adjectives describing it must be feminine. Here, the plural adjective afiladas perfectly matches the feminine plural noun hachas.
If I only bought one sharp axe, how would I change this sentence?
Compramos is the present tense for 'we buy'. Why is it translated as 'we bought' here?
For regular -ar and -ir verbs, the nosotros (we) form is exactly the same in both the present tense and the preterite (simple past) tense. Compramos can mean 'we buy' or 'we bought'. You have to look at context clues to know which one it is. Here, the word Ayer (yesterday) clearly tells us this action happened in the past.
