I keep coming to this in my story. "I walked toward..." I'm reviewing my work and I keep finding that I have written "towards." Which is it? Is it simply a matter of casual versus formal writing?
Google toward vs towards, and you'll find good coverage of this issue. There are also prior threads on it here.
Either is fine, it's like spelling color colour. Just depends on what form of English you're using. However, I generally use towards with gerunds and toward with past tense. I jumped toward her. I was jumping towards her. Just something I noticed I do.
Although if you look at the ngram curves on grammarist (which you'll find if you follow Cog's advice) it looks as if non-US usage might be starting to switch over too, about a century later than US usage did.
