The question
Portmanteau seems to apply in cases like:
- Phablet - Bigger than a smart phone, smaller than a tablet.
- Smog - Smoke and fog.
- Vlog - Video and blog.
There must be another word for things that have a more phonetic feel:
- Shizzle - recently added to the OED, which sort of feels like sure with fizzle in it?
Or for a word that has one letter replaced by another letter or letters, but where the pronunciation stays the same:
- Comix - Web comics?
