Is there a げ used for N adjectives?

bamboo4, I thought 大人げない is a good example but is this irregular? This is different from others. 大人げ is always followed by ない. 大人げ が ない or 大人げない.

Formed from Adjective base + ge (e.g. i-adjectives lose final i)
Ab = Adjective Base

Amatuka

I'm not sure, but I'd guess 大人げない follows a similar pattern to 何げない、さりげない、すげない etc., rather than following this grammar pattern. Adjectives combined with げ inflect as ーな adjectives. 大人げない doesn't seem to work that way.

〜げcan be used for i- and na-adjectives
