you have too sight the last name of the author and the page number whether it is a quote or paraphrased. the only time you don't have to is if you include it in the sentence.
Example for when you don't have to cite in text:
On page 13 Martin says, "blah blah bah bluh bleh blah"
... otherwise just put the citation in parentheses after the quote/paraphrase like so: (Martin,13)
1. Meaningful parts means words that make sense; words you can understand. Flagpole would become flag and pole.
2. What does flag mean? A piece of cloth, usually rectangular, of distinctive color and design, used as a symbol, standard, signal, or emblem. What does pole mean? A long, cylindrical, often slender piece of wood, metal, etc.
3. A symbolic cloth on a pole, or meant to be on a pole, would be called flagpole.
4. Use these steps and summarize them in your own words.
Hope this helps!
