Portmanteau Words

Portmanteau words are a combination of two other words to form a new word with a combined meaning. 

For example, blog is a combination of web + log = blog.  

Some other common portmanteau words: brunch = breakfast + lunch, camcorder = camera + recorder, spork = spoon plus fork. 

I recently heard some new fun ones that I might start using: jelly = jealous + happy, and voluntold = asked but also told (expected) to volunteer.
