To define a word try looking it up and noting the contexts that it is used in. You can do this with the english but it is way more insightful to do it in the original languages. Use a key number search or search for a root or lemma. Then use the analysis window to see how it has been translated. This can help you understand what is meant in the bible when a word is used.
Key number g2316 is used 6 times as "god". Use the command [Key G2316]@=god to see those occurrences. You see that the writers used the same word to refer to false gods, idols, a type of being, and even satan by seeing what these contexts have in common we see that the word "god" is not simply a name but a position or function.
This is just a place to start a word study of course. And where the fun begins on the journey to mine for God's truth.
You may also find it helpful to look up the equivilant word in the Hebrew or the LXX.
But in short yes christ(greek)/messiah(hebrew) is also a title.
It would make a good exercise to see if you can demonstrate that for yourself.
Remember God is a rewarder of those who seek Him.
Have fun and don't forget to pray for the Holy Spirit's leading before studying.
