Tenser, says the Tensor has an interesting post on the use of “slouch” as a verb of motion, as in William Butler Yeats's poem "The Second Coming:"

    And what rough beast, its hour come round at last,
    Slouches towards Bethlehem to be born?

The Tenser did a Google search and found 285 variants of slouching toward something.  Slouching toward Gomorrah seems to be very popular and frequently misspelled. (The Tensor found nine different spellings).   Slouching, when used as a verb in motion, creates a vivid word picture -- I will have to remember to use it more often. 

The slouching information was interesting, but read the Tenser’s discussion of “toward” and “towards,” which is linked to the slouching post.  Every time that I use either of those words, I hesitate because I assume that one is correct and one is not.  Based on another Google search, The Tenser found that “toward” is more common in American English and “towards” is more common in British English:  

It does appear that exclusive use of towards is more than ten times as common as exclusive use of toward in British English, but they're about equally common outside of the UK, and in .us domain web sites, toward is about twice as common as towards. Pages with mixed usage are always the least common.

So, boiling down this data to an oversimplification: if you use towards your prose will seem slightly more British to American readers, and less obviously American to British readers.

That is consistent with the OED, which lists both words, but the entry for “toward” mainly just refers to the entry for “towards.” 

When I am not sure of how to use a word, I usually try to find ways to avoid its use.  That’s how I have been with “toward” and “towards,” but not any more. 

In The Tenser’s post on “toward” and “towards,” there is a link to another interesting post on “word moments.”  Read it here.
