"Las estudiantes hablan inglés."
Translation:The students speak English.
Same here, duolingo threw a curveball but thankfully I guessed right. Hablar sounds like the verb itself ("to speak") so I guessed it may have been hablan!
Hablar = to speak, to talk
Habl / ar
Habl + o = I speak
Habl + as = you (familiar) speak
Habl + a = he, she, it speaks; you (formal) speak
Habl + amos = we speak
Habl + an = they, you (plural) speak
Las estudiantes can be replaced with 'they' and just like with ''you, I, he and she'', 'they' adds it's own addition to a verb. It is an 'n'. So that explains hablaN instead of hablo/habla/hablas/hablar.
