Usage Note: Most American English dictionaries list -wards as a spelling variant of the directional suffix -ward. Accordingly, two variants are provided for most of the adverbs that end with this suffix: backward/backwards, toward/towards, upward/upwards, and so on. Although both variants are considered acceptable, the -ward suffix is more common in American English, whereas the -wards suffix is more common in British English. This distinction is more prominent in edited prose than in casual writing or speech, possibly because many American copyeditors follow style manuals that recommend or prescribe the -ward variant. Despite this dialectal differentiation, there remains significant variation in usage among individuals and even among the different -ward words themselves. This variation is evident in the results from our 2012 usage survey: backwards and towards were deemed acceptable by 72 percent and 69 percent of Panelists, respectively, but only 38 percent found forwards to be acceptable. Note that for those -ward words that also function as adjectives, the form without the s is standard: a backward look; a westward journey.
