"When I use a word." Humpty Dumpy said, in a rather a scornful tone," it means just what I choose it to mean- neither more nor less"
Writers they can use words inventively and even make up words, but only if they have command over their prose. Wrangling words means knowing their current means, how context can change meaning, (think-gay) as well how they sound so that reading flows. Although science fiction and fantasy writers often make up words, they still have to worry about how they sound and fit in the worlds they create.
Humpty Dumpty on about words: "They've a temper, some of them - particularly verbs: they're proudly - adjectives you can anything with,but not verbs-however I can manage the whole lot of them!"
Yes, verbs are exacting, that is the action ones. Passive verbs should be left in first drafts and replaced. Action verbs (are you walking, running, skipping?) puts the reader into the story. Reliance on easy adjectives and especially adverbs puts flab on your writing. Instead look past the easy to find the unique phasing that will make your writing memorable.
