IPA: /ˈʌp.doʊ/
KK: /ˈʌpˌdoʊ/
A hairstyle where the hair is arranged up and away from the face, often secured with pins or bands.
She wore her hair in a beautiful updo for the wedding.
Updo → The word 'updo' is formed from 'up' (meaning in a higher position) and 'do' (from Old English 'dōn', meaning to make or to do). An updo refers to a hairstyle that is arranged or made in a way that keeps the hair up and off the neck.
Think of hair being styled 'up' — that's why an 'updo' is a hairstyle that keeps hair in a higher position.
