@SMickey,
In the following, the second one assumes you know his destination . The first one says he was heading towards his office but the destination is not assumed . He might have been going to the shops near his office .
A. When I saw Jake, he was walking toward his office.
B. When I saw Jake, he was walking to his office.
If you wished to talk about after his arrival you would say :
He walked TO work . At work, he noticed his shoes were muddy .
If you wished to break up the trip you would say :
He walked TOWARD work but was stopped by construction .
C. He walks to work every day. (O)
D. He walks toward work every day. (X)
Quote:C is fine, but native speakers don't say like D,
which proves that 'toward' is not interchangeable with 'to'.
This is incorrect for reasons above . Native speakers do say D, but TO and TOWARD are not interchangeable . Ask yourself do you want to break and talk about the travel...if so use toward . If you want them to arrive at their destination and then talk about what happened next, use to .
Toward is more formal, say for report writing, whereas towards is more informal say for a novel . The British almost always use towards regardless . Modern trends in universal English is toward towards .
