Dealing with animation, I often want to described a surface that can be generally traversed as "traversable," but every time I type that word anywhere, like MS word or including stack exchange, it says it's not a real word, though I see no reason why it shouldn't be. What other word could I use to capture a variety of methods of locomotion allowing the passing through or over a landscape?
Because "walking" is too limited and somehow no one made "travelable" a word either. Clearly this usage is a simple and common occurrence, yet somehow, English doesn't appear equipped well enough to deal with it.
