Why if you spell toe its prounced toe. add a ws it is then as taves but spelled toews?

This is a great question! You're noticing a very common pattern in the English language: the inconsistency of spelling and pronunciation.

Here's why it's like that:

* English has a complicated history: Our language has borrowed words and sounds from many other languages over centuries. This means we have different ways to spell the same sound, and different sounds spelled the same way.

* The "Great Vowel Shift": This was a major change in pronunciation over several centuries in English. Some vowels that used to be pronounced one way shifted to different sounds. This resulted in inconsistencies between how words are spelled and how they're pronounced.

* "Silent" letters: We have a lot of letters in English that are not pronounced, like the "e" in "toe" or the "w" in "know". These letters can be silent or they can influence the pronunciation of other letters in the word.

In the case of "toe" and "toews", the "w" is pronounced because it's at the end of the word, not because of any rule, but because of historical changes in pronunciation. This kind of inconsistency is just a part of learning English!
