The phrase "doth best" is not a common phrase used in modern English. However, it can be understood by breaking down its phonetic transcription in IPA (ðʌθ bɛst). The word "doth" is an archaic third-person singular form of the verb "do." The use of the letter "th" represents the voiceless dental fricative sound. The word "best" is spelled phonetically as /bɛst/, meaning it is pronounced with a short "e" sound followed by a voiceless consonant. The phrase "doth best" may be interpreted as doing something better than others.
The phrase "doth best" is derived from Middle English and has its roots in the verb "doth" and the adjective "best".
The word "doth" is the third person singular present tense of the verb "do" in Middle English. It comes from the Old English word "dōþ", which also means "does" or "performs".
