Ojalá hint: Olajá
I'm new to this whole duolingo thing but I didn't find this hint particularly helpful.
Is this me being stupid or an error? All the other hints gave hints (i.e. translations).
That link doesn't give much, but there's a long list of Spanish words of Arabic origin here: http://en.wikipedia.org/wiki/Arabic_language_influence_on_the_Spanish_language
ojalá: "I hope"; "I wish that...". From law šhaʾ allāh "God willing."
