Etymology
the word 'best' originates from the old english 'betest,' which was the superlative form of 'bōt,' meaning 'remedy' or 'advantage.' this old english term evolved from the proto-germanic superlative 'batistaz,' itself derived from the proto-indo-european root 'bʰed-,' meaning 'good.' the semantic journey saw the original sense of 'most advantageous' solidify into the modern meaning of 'of the highest quality' or 'most excellent.' its irregular formation, supplanting the expected superlative of 'good,' is a common feature in core vocabulary across many indo-european languages.
Analysis
the word 'best' is a suppletive form, meaning its comparative/superlative relationship to 'good' is not formed by a regular morphological process. it is a simplex word derived from old english.
