"The women like large cafés."
Translation:La virinoj ŝatas grandajn kafejojn.
It is because of the accusative form. When the substantive/adjective is preceded by an action (in this case, sxatas), the word/s get an n:
- La kafo (no action)
- La virino trinkas kafon (kafo is the thing that la virino drinks. The declination is accusative, so > kafon).
Hope that helps.
Every time you find a verb ask yourself "what? " what is she eating? , what is does he like? , what do they see? If you can indeed ask that question and there's an answer in the sentence: "she eats apples, he likes the letter, they see her" then that word (and any adjective that refers to that word) must have - n
Because adjectives get accusative declination too. As Sarodriguezca said, any adjective that refers to the "accused" word must have -n. Example:
- Vortoj longaj kaj belaj. (Long and beautiful words) [no accusative, there's no action]
- Mi vidas vortojn grandajn kaj belajn. (I see long and beautiful words) [accusative, there's an action (seeing) happening on the object].
Hope it helps.
