I have people asking me why some of thier posts are showing large gaps between lines, different fonts, different sizes and some times weird and wonderful symbols all over.
It’s because Microsoft Word is a web pretender and thinks it can write HTML code for websites. So when you attempt to copy and paste, it pushes into the html section reams and reams of bloated useless code that ultimately affects your layout and your post.
Up until recently, the only way around that was to writing directly into wordpress. Not an ideal solution, WordPress has a dictionary, but it isnt the level of Microsoft’s Word. Thankfully you can now do both, type away in Word, spell check etc then look for this button 
in the group of buttons above the enter post window. Now you can paste your Word content in there and voila, no more symbols and mismatched type!
If you dont see the symbol above, look for this button 
called the kitchen sink, click that, it drops down or hides all the buttons.
What this will achieve, is that you can bold, underline, italicise, add links, indent all within Word and it will come across intact.
You shouldnt use this to paste images, images should always be entered directly into WordPress, however once you have the text done, adding images is the easy part.
