What does best mean?
'Best' is the superlative form of 'good', describing whatever surpasses all others in quality, value, or desirability. It functions chiefly as an adjective ('the best solution'), an adverb meaning to the greatest degree or most effectively ('she sings best in the morning'), and a noun referring to the most excellent option or to one's maximum effort ('I did my best'). Less commonly, it serves as a verb meaning to outdo or defeat someone. Because it expresses the top of a scale of evaluation, it carries strongly positive connotations and appears constantly in praise, recommendation, and competition. Idiomatic uses abound, from 'the best of both worlds' to 'at its best'. Derived ultimately from Old English, it shares an irregular comparison with 'good–better–best' inherited from ancient Germanic roots, making it one of the most enduring and versatile evaluative words in English.
Surpassing all others in quality, excellence, or desirability; superlative of good.
"That was the best decision we ever made."
Used with 'the' when singling out a specific item; can appear without an article in fixed phrases such as 'best wishes'.
Most excellently or advantageously; to the greatest degree.
"He knows best how to handle these situations."
The most excellent person or thing; also, one's utmost effort.
"She always does her best."
In the effort sense it typically follows a possessive: 'my best', 'their best'.
To outdo, defeat, or get the better of.
"She bested her rival in the final round."
Somewhat literary or playful in register; 'beat' is the ordinary choice in casual speech.
Rare and mostly confined to commercial contexts such as publishing, where 'bests' may denote multiple bestselling titles.
"The publisher's list featured several of the year's bests."
'Best' has been beating out every rival for over a thousand years — it started life as an Old English irregular superlative and simply never lost the crown.

Etymology of best
Old English had 'betst' or 'bet(e)st', the superlative of 'good', built on a Proto-Germanic root also seen in 'better' and the archaic word 'boot' meaning remedy or advantage. The vowel change from the base 'good' reflects ancient ablaut patterns rather than regular derivation. Cognates appear across the Germanic languages, including Dutch 'best' and German 'am besten'. The word has remained remarkably stable in form and meaning for over a millennium.
