Questions & Answers about taeksireul tago gonghangeuro baro chulbalhalgeyo.

What does -를 in 택시를 do here?

-를 is the object marker. In 택시를 타다 (to ride/take a taxi), the noun 택시 is treated as the object of the verb 타다. So 택시를 = a taxi (as the thing you’re taking).

Why is it 택시를 타고 and not 택시를 타서 or just 택시를 타요?

-고 connects actions in sequence: take a taxi and (then) depart.

• 택시를 타고 공항으로 출발할게요 = I’ll take a taxi and head to the airport.
  You could also use -아서/어서 (타서) to mean by doing X, (I) do Y, but 타고 is very natural for and then / by means of.
  If you say only 택시를 타요, it just means I’m taking a taxi (no mention of leaving for the airport).

Does 택시를 타고 mean “by taxi” or “and then take a taxi”?

In this kind of sentence it commonly implies both method and sequence:

• method: go by taxi
• sequence: take a taxi, then leave/head out
  Korean often uses N을/를 타고 to express transportation: 버스를 타고, 지하철을 타고, 택시를 타고.
