The word "枫树" is formed by combining the character "枫", meaning maple, which is a phono-semantic character composed of the radical "木" (wood) indicating its category and the phonetic component "风" (wind) suggesting pronunciation, with the character "树", meaning tree, also a phono-semantic character with the radical "木" (wood) and the phonetic component "对". Together, they create a compound noun where "枫" specifies the type of tree and "树" denotes the general category, resulting in the meaning "maple tree".
