Are yet and but same?

Dear Student,

‘Yet’ is similar to ‘but’. In sentences where the part coming after the conjunction is of an unexpected or a surprising nature, any one of them can be used. However, when the part following the conjunction is not of a surprising nature, it is always safe to use ‘but’.

For example:

I would like to go for the wedding, but I have important work to complete.

Let us replace ‘but’ with ‘yet’ in these sentences.

I would like to go for the wedding, yet I have important work to complete.

These sentences do not make the same sentence as the previous two sentences. Therefore, whenever in doubt, use 'but' instead of 'yet'.
