Learn English – Dissatisfaction towards/with/to

The Common Errors in English Usage site mentions:

These two words are interchangeable, but “toward” is more common in the US and “towards” in the UK.

Some people, probably influenced by “forwards,” write “torwards” instead of the correct “towards.”

The merriam-webster simply list both words under the same entry, with similar ethymology:

• toward: Middle English toward, from Old English tōweard facing, imminent, from tō, preposition, to + -weard -ward
• towards: Middle English towardes, from Old English tōweardes, preposition, toward, from tōweard, adjective

All three are actually correct in English usage, ambiguous as that seems. No matter how you word it, the thing you are providing is the actual, functional direct object, while the person or thing you're providing it to is the indirect, even though the words might not make that obvious.

This would be less ambiguous in a language that had a separate dative case (like Latin or, I believe, Russian), where the thing or person you were giving something to would always be suffixed differently than the thing you were providing (which would be in the accusative case), and the word order wouldn't matter because noun cases would tell you which was which.
