The quality or state of being anile; silly or weak behavior associated with old age.
From 'anile' + '-ness', the common English suffix for creating abstract nouns. This follows the standard pattern of forming nouns from adjectives in English since at least Middle English.
The suffix '-ness' is one of English's most productive tools for noun-formation, and it's been working the same way for over a thousand years—you could coin 'blueness' or 'silliness' even if the specific word didn't exist in any dictionary.
Derivative of 'anile'; compounds the gendered dismissal of aging women by nominalizing a term that conflates femininity with diminishment.
Replace with 'advanced age,' 'senescence,' or condition-specific terms that don't embed gender bias.
