One of my favorite computer desktop tools is called WordWeb – free version. When writing I use it several times a day. It’s brilliant for checking word meanings & spelling no matter which software I’m using at the time.
It has a small footprint and the icon sits in the desktop tray at the bottom right-hand corner of the computer screen ready to fire into action. It saves so much time especially when using software that lacks a spell checker.
WordWeb also includes an audio tool in case of being unsure how a word should be pronounced. You can download the free version here: WordWeb
