You can give as many botanical definitions of the word "tree" as you want but it will just be a word defined by other words that are themselves defined by yet more words that are.... If you tried to dig for meaning all you'd find is a endless loop, it would just be a game where words are manipulated according to the rules of botany until somebody forgot about definitions and pointed to the ASCII string "t-r-e-e" and then pointed to a large photosynthesizing organism made largely of cellulose that exists in the physical world. Then even a martian would notice a correspondence between this game of manipulating symbols called "botany" that humans had invented and the way these large photosynthesizing organism made largely of cellulose live.
