Nobita is eternally a grammar-school student.

Radical:

Same as 園, 遠 has the 袁 phonetic. That's great, because otherwise I would never remember that 遠 also has a reading of えん, as in 公園.

Shinnyou on the left and bottom. By going on the road, you can get far away.

Important:

Be careful. The long "o" sound in 遠い is "to" + "o", not "to" + "u". When typing it in, you'll never be able to type 遠い by typing とうい.
