It means "the year of the blue horse." Here's a quick tip for in the future. "청," means blue. And "마" means horse. That's why it is 청+마 = 청마 = Blue horse. I don't know if you know, 바지 means pants. so 청+바지 = Blue jeans. 청 and 마 can have various meanings as well, so don't assume EVERYTHING with 청 means blue and 마 a horse. Cheers!

You write like this as 청마의 해. You need to have a word spacing(띄어쓰기). In Korean, the word spacing is important. 청마의 해 means the years of a blue horse.In Korea, we use Chinese zodiac sign when we have each year. Above a comment is a really good explanation, read it. and then you will understand it more.

It is complicate explaining it... As another asker said, this means 'the year of blue horse'. I explain the meaning of 청마해. In Korea, people used special year cycle every 60 years. This is combined 10간 and 12지. 10간 is 갑, 을, 병, 정, 무, 기, 경, 신, 임, 계. Especially, 12지 means each animals, 자(rat), 축(cattle), 인(tiger), 묘(rabbit), 진(dragon), 사(snake), 오(horse), 미(sheep), 신(monkey), 유(chicken), 술(dog), 해(pig). And combining 간 and 지 one by one in regular sequence. For example, 갑자년(갑 + 자 year), 을축, 병인, 정묘, 무진, 기사, 경오... So 2014 is the years of 갑오년. '오' is the horse, so this is the year of the horse. And... second. Why is the blue? From the ancient, 10간 have some meaning of each colors. 갑and 을 mean blue, 병 and 정 mean red. 무 and 기 mean yellow, 경 and 신 mean white. And 임 and 계 mean black. So 2014 is 갑오년, as I said. 갑 means blue. So, 갑오년 is the year of blue horse.
