Wave to vs. Wave at: What's the Difference?

'Wave to' and 'wave at' are both expressions used to describe the action of waving one's hand in greeting or acknowledgement. However, there is a slight difference in how they are used:

1. 'Wave to' is used when you want to indicate that you are waving in the general direction of someone or a group of people. It is a more general greeting and does not necessarily imply that you are specifically trying to get their attention.

Example: 'I saw my friend across the room and waved to her.'

2. 'Wave at' is used when you want to indicate that you are specifically trying to get someone's attention by waving in their direction. It implies a more intentional and direct greeting.

Example: 'I saw my friend across the street and waved at him to get his attention.'

In summary, 'wave to' is a more general greeting, while 'wave at' implies a more deliberate attempt to get someone's attention.
