What is the difference between "one-to-one" and "one-on-one"

Hi,

Is there any difference in meaning between “one-to-one training” and “one-on-one training”?

Many thanks,

Hi Torsten,

I would feel “one-to-one training” and “one-on-one training” are almost synonym. But I would like to make a wild suggestion that ‘one-to-one’ gives off a sense of equality under a certain circumstance. That is, the two parties in some case are not necessarily of a trainer-and-trainee relationship. They could be both trainees. On the other hand, ‘one-on-one’ sounds like a trainer and a trainee.

Just my two cents.

Best regards,

Haihao
