First off, I must say there are very few errors on this site. That said, I found one.
It's on this page: Link
One of the words in the Example Sentence is linked to the wrong word.
Example Sentence:
しかし、たいへん息子を欲しがっていました
欲しがっていました is linked to the adj. hoshii (欲しい) when it is actually the verb hoshigaru (欲しがる) 「欲しがって」 in the Te form and, our little friend, the auxiliary verb Iru (居る) 「いました」 in the Past polite form.
Now, I bet that if they would have taken the time to link Iru, they would never have mis-linked the other word
ありがとう,
