IPA: /ˈɡɪrliər/
KK: /ˈɡɪrliər/
More characteristic of or resembling a girl, often in a way that is considered feminine or delicate.
She wore a girlier dress for the party than she usually does.
'Girlier' is formed from 'girl' (from Old English 'gyrl', meaning a young female) and the suffix '-ier' (meaning more). The word 'girlier' means more like a girl or having more characteristics typically associated with girls.
Think of 'girl' as representing a young female and '-ier' indicating a comparison, so 'girlier' means having more qualities of a girl.
