I am asking about the keywords that could make anyone feel fantasy.
it will be better if every one who will see this post could tell me what their feelings are or express their feelings in one keyword that delivers fantasy. Thanks in advance :)
I'm not going to give you words to describe fantasy - that's not the point of this site. Instead, I'm going to introduce you to what a lexical field is. A lexical field is a 'family' of related words. This is also known as a semantic field.
For example, here are some words in the lexical field of nature:
By coming up with words relating to one lexical field and using that in your writing, you can reinforce a certain mood. For example, you can restrict yourself to using lovely words, or sad words, and that will help reinforce the mood of your novel.
What I suggest you do, is think of some words you associate with fantasy. Create a lexical field of fantasy words to use in your writing. You're looking to make the setting as accurate as possible to what is in your mind. If it's sad fantasy, use sad words, etc.
Due to this, I don't believe it's right to just hand out words to you. It depends on many factors, and you should decide for yourself. Use a semantic field to assist you in creating a true sense of setting within your writing.
I hope this helped you.
Choose words and symbols to illustrate your fantasy, rather than something generic.
First off, there are a number of free online tools for exploring words' synonyms, connotations, and impact. One I like is: http://graphwords.com
Secondly, if you figure out what makes your fantasy unique, and find words that illustrate and support that, you'll be telling your own story, rather than some generic (and IMHO thus more boring) story.
So if your fantasy involves, say, magical trees, find/search for words related to trees, folktales about trees, tree spirits (dryads), origins of Christmas trees, etc. Use the resulting info to 'color' the world your story takes place in and its characters. If dragons are a focus, make word/concept lists to support flying, fire, jewels, caverns, treasure etc.
And you can do this with names (though best to avoid being obvious about it.) For example, 'Thorin Oakenshield' gives some character hints that 'Thorin Jones' just doesn't.
Words individually do not give the feeling of any genre. It is how you put them together to create a picture in the reader's mind. Just as a painter may use the same pallet of colors to paint a unicorn or a cart horse, so an author can use the same pallet of words to paint a fairy palace in the air of a gritty tenement in New York.
Read the opening of some of the great fantasies like Wind in the Willows or LOTR and you will find that they use very ordinary words. It is how those words are combined to produce images that makes the difference.
