This podcast episode from "The English We Speak" explains the English idiom "go-to," meaning a preferred option or choice in a specific situation. The hosts, Feifei and Phil, define the term, provide examples of its usage as both a noun and adjective (e.g., "my go-to for soup," "go-to options"), and illustrate its application through listener examples. Listeners learn how to use "go-to" in various contexts, expanding their English vocabulary and understanding of idiomatic expressions. The episode concludes with a promotion for another BBC Learning English series, "The Pronunciation Lounge."
