타고 means 타다(ride)+ 그리고(and) =타고 for example, 버스를 타고 학교에 갔다. I will explain about another word 먹고.. 먹고 means 먹다(eat) + 그리고(and)= 먹고 for example, 밥을 먹고 공부한다..

Maybe you mean "타다"(Ta-da). That means 2 different things. First, it means 'ride'. For example, 'riding bicycle' is ' bicycle을(ul) 타고(Ta-Go)' Second, it also means 'burn'. 'The house is burning!' is '집이(Jip-I / House) 타고(Burning /Ta-go) 있다(is / It-Da).
