In the past, Korean didn't use spaces and used vertical writing right to left. After Korean war, we use spaces... Anyway, In English, there is no postposition (조사 助詞) likes 은/는/이/가 ... For example, English : Tom loves jane. S V O Korean : Tom은 Jane을 사랑한다. S O V In English there are located only words, but in Korean words are combined postposition. If you are confused how to put into spaces in sentence, Just put the space after word+postpostion. It may works well. That is easy way to solve your question. Try to put spaces into following sentences. 1) I like you / 나는너를좋아한다. 2) I'm a student / 나는학생이다.

A very useful explanation on Korean spacing http://www.talktomeinkorean.com/?s=spacing By modern rules, Korean spacing _should_ look a little similar to how English is spaced (spaces between most words). However, in colloquial (non-textbook) Korean, it's not uncommon to not put spaces, or put very few. (Though, it might look a just a little uneducated/informal) Some real-life examples from text messages: http://www.youtube.com/watch?v=36nPCjm073k#t=14m33s As you can see at 14 minutes and 33 seconds, their text messages completely lack spaces. As you begin to understand Korean better, you will understand it even without spaces. Thinks like ㅋㅋ (laughing), ^^ or ~ act sort of like spaces. (taken from the Korean TV show "SNSD and the Dangerous boys" http://en.wikipedia.org/wiki/Girls%E2%80%99_Generation_and_the_Dangerous_Boys 소녀시대와 위험한 소년들 Also, if you are learning Korean on your own (the same way I am), I highly recommend using Talktomeinkorean.com and http://korean.sogang.ac.kr/, both are free websites that will teach you almost everything you need to know. Some more real-life Korean spacing examples: http://www.youtube.com/watch?v=moP4imfsT3o#t=7m38s at 7 minutes and 38 seconds (this one has a few spaces, but also leaves out many spaces) http://www.youtube.com/watch?v=36nPCjm073k#t=24s at 24 seconds and more at 38 seconds

Just some general rules. 1. 조사는 그 앞말에 붙여 씁니다. (ex. 조사: -만큼, -대로, -뿐, -가, -이다, -을, -의, -에서, -로, ....) (1) 콩나물만큼 길다. 콩나물(Noun) + 만큼 = 콩나물만큼 >> '콩나물'의 바로 뒤에 오는 '만큼'은 앞의 명사에 특별한 의미를 보태어 주는 보조사입니다. 따라서 붙여 써야 합니다. (Noun + 만큼 = 콩나물만큼) 2. 의존 명사는 뛰어 씁니다. (ex. 의존 명사: 만큼, 대로, 뿐, 수, ....) (1) 배운 만큼 안다. (배운V만큼) ( 배우(다) +ㄴ )배운 + 만큼 = 배운 만큼 (2)노력할 만큼 했다. (노력할V만큼) ( 노력하(다) + ㄹ )노력할 + 만큼 = 노력할 만큼 >> '만큼' 앞의 용언의 받침이 'ㄴ'과 'ㄹ' 둘 중 어느 하나로 끝났으면 띄어 쓰면 됩니다. (Verb의 어간 + ㄴ/ㄹ) + 만큼 = 배운V만큼, 노력할V만큼 3. 단위를 나타내는 명사는 띄어 씁니다. (ex. -개, -살) (1) 한 개 (한V개) (2) 열 살 (열V살)
