Answer:
Online dictionaries
Explanation:
When dealing with English, you have many choices, but I would recommend using the most important references in printed dictionaries:
For US English spelling, I usually go with Merriam-Webster
For UK English spelling, I always use Oxford Dictionary
Sometimes, I work with Wikipedia... it's nice to have pictures and other related words... and in different languages too.
And there are many other online dictionaries too.
