"The lion is eating a boy."
Translation:האריה אוכל ילד.
Thanks, I knew it was the male form but it's got a hey & is plural as a female. Thanks for quick response. I found this on the discussions: Some masculine words have a feminine plural form - like in this case, אריה->אריות, or כיסא->כיסאות, or חלון->חלונות; and some feminine words have a masculine plural form, for instance שנה->שנים, ביצה->ביצים, מילה->מילים. These are considered irregular, and adjectives referring to them would all be conjugated according to the word gender. So in the same way that one would say ביצים קשות, (hard-boiled eggs), one would also say האריות יפים. It's rather unfortunate that there isn't a particular rule to these irregular words, so you just have to memorise them.
