You have no other way out but to find the meaning of that word in the dictionary either online or offline. But since you're using your phone yo read the news, I'll suggest you should try using an offline dictionary to make your work easier. On the contrary, you can try to relate the word and try to thin what the editor was trying to mean. And then, you can confirm it in the dictionary just to ensure you're right. Trust me, at that pace of consulting the dictionary, you'll go very far with your vocabulary. You'll consult your dictionary very rare times and from there you won't be spending much time on them. Also, you can try consulting someone you is very good when it comes to vocabularies and in fact they'll be good to help because they'll be expanding there knowledge.
