Edit: This is a duplicate of How does tone sandhi apply in people's names?
I learned the rules for pronouncing tone pairs, I know that for a sentence like 我买花 the two third tones become a second and a third tone, the pronunciation would be wó mǎi huā. I learned this from This site
I came across this sentence: 我可以看得很清楚. There are three third tones at the start of the sentence 我可以 (wǒ kěyǐ), how do the tones change in a case like this?
