The quality or condition of being a girl; girlhood or a characteristic behavior associated with girls.
From girl + -ery (noun suffix forming abstract nouns), following the pattern of words like slavery, drollery. The term is rare and mostly historical.
Words ending in '-ery' often carry a slightly judgmental tone—girlery, like 'drollery' or 'trickery,' suggests the behavior is characteristic or perhaps excessive, showing how suffixes add attitude to words.
