What 좋 means
It is a stem, not a standalone sentence. The full word 좋다 calls something good or satisfactory, and its inflections can give permission, approval, or liking. In 이 영화가 좋아, the film is pleasing; 좋아하다 instead marks the liked thing with 을/를. So read the ending and particles before picking an English gloss.
Hangul was made to write Korean for people who could not read Chinese characters: its first creation record is from 1443, and the explanatory book appeared in 1446. This word’s spelling runs from 둏다 in 15th-century texts through 죻다 to 좋다 from the 19th century onward. The older spelling covered both “good” and “improve, recover”; modern 좋다 centers on good and pleasing.
The whole 좋다 family is ordinary Korean; lone 좋 is clipped and depends on context.

2Can 좋 be broken into separate letters?
Yes. It can be one precomposed block or an equivalent jamo sequence; fonts may place the pieces differently, while a Korean IME normally builds one block.
Why does 좋 sound different in 좋다 and 좋아?
It depends on the ending. The dictionary gives 좋다 as [조ː타] and 좋아 as [조ː아], so the block has no single pronunciation outside a word.
