Here are some basic words for transportation in Korean. We may do a part 2 for these as there are a few more we want to cover. Words in this infographic:
자동차 (ja-dong-cha) = car (can also be shortened to just 차 at times)
버스 (beo-seu) = bus
트럭 (teu-reok) = truck
자전거 (ja-jeon-geo) = bicycle
기차 (gi-cha) = train
택시 (taek-si) = taxi
배 (bae) = ship/boat
지하철 (ji-ha-cheol) = subway
비행기 (bi-haeng-gi) = airplane
Remember that romanization is only a tool! Try not to depend on it too much and try learning the Korean alphabet and how to pronounce the letters properly to have an easier time learning Korean.
