Lost In Definition

I struggle to define the definition between buddy and friend and mate Lost in definition i have been of late Though seemingly similar the words buddy, mate and friend In them may vary in meaning why otherwise pretend The difference between musical, lyrical and libretto may not seem that great But in meaning they vary as much as buddy, friend and mate Words that apply to similar things may vary in meaning would you not agree At least anyhow this is how it does seem to me Lost in definition a problem that is mine Between words with similar meanings i find it hard to define The word canine can apply to a dog as well as to teeth And though of similar meaning a difference between pride and conceit The words lost in definition to me does apply That i am not a bright person i will not deny.
