<upd_detl>In Kenkyusha this is used in the same manner as "らしい" when added as explanation to a noun. You give a good example with the following entry:-
馬鹿げる 【ばかげる】 (v1,vi) to look foolish
I guess that you would see a better description than I have used above, but if you include it I am sure that it would help the novice to understand.
It is not easy to give Google hits because searching for "げる" does not act as a good tool because of the wide use of the search in various general ways, for example: "あげる".</upd_detl>

<upd_detl>I can't find examples of where this is used in the manner you describe. It's not mentioned in any of the language references I have. Can you provide some examples from Kenkyusha?</upd_detl>

<upd_detl>The outcome which I submitted was like a combination of several things. I came across "馬鹿げる" which I looked up in Kenkyusha. In that dictionary is showed "馬鹿" followed by alternatives, namely: "な" "げた" "らしい"　with the common meaning of "foolish, silly, supid, ridiculous, absurd".

I understood "な" and "らしい", but I did not understand "げた" so I checked on your site and found "馬鹿げる". Then I thought that it was a possible suffix, e.g., like "がる (suf,v5r)".

I searched around further but I could not find anything useful. However, because "馬鹿げる" appeared on your site along with "馬鹿" and "馬鹿らしい" and because of the implied similar meanings given in Kenkyusha, I thought that I would make the submission [thinking that it would be a simple addition based upon its absence on the basis that everyone knows the obvious except the novice].

Following your comment, I checked on various other dictionaries at the British Library. Shogakukan gives indications of meanings/usage for "馬鹿げる" as "馬鹿らしくみえる"　and "馬鹿げた話". However, this only takes us back to where I started.
"げる" as an entry in Shogakukan is explained as "[動]　盗むことを言う、盗人仲間の隠話。"

"ける馬"　as an entry in Shogakukan seems to relate to a horse which rages, but that does not take the matter any further.

Perhaps what seemed to me to be simply a missing suffix is just an addition to one noun, the horse!!

Sorry to have wasted your time on this one.</upd_detl>
