Informal or dialectal term suggesting a tendency toward admitting or allowing; somewhat open or receptive.
From admit plus -y, a suffix meaning 'characterized by' or 'full of,' forming adjectives informally. The -y suffix comes from Old English and Germanic roots, commonly creating colloquial adjectives like muddy, grumpy, or friendly.
Admitty is so informal and rare that most dictionaries don't even include it—it's the kind of word someone COULD create by the rules of English, but nobody really uses. It shows the living, creative nature of English suffixation!
