What is the difference between the verbs "call" and "ring" in the meaning of telephoning? For example:
- I will ring you back shortly.
- I will call you back shortly.
The two words are identical in meaning here. The usage of call is obvious, while the usage of ring simply originated from the noise a telephone makes when you call someone.
Ring is definitely a more informal word, so if in doubt, use call.
Ring is generally used in the UK, while call is used in the US. There's no difference in meaning.
Ring is very common in Australia and New Zealand, and probably somewhat frequent in the U.K. and Ireland, but call is basically always used in the U.S.
I've heard "give * a ring" in the US, but never "ring *"
