Additionally, in my modern Irish dictionary I find:
Seang : slim, slender, meager
Seanga'n (supposed to be a fada over the a) : an ant
Sean : old
Sai'nn (fada over the i): a trap
Sai'nnigh : to trap

I am curious as to whether any of the modern terms might be
derivatives of Sengann.

Sincerely,
Aydan

of meet, meet, and mete.... It is greatly appreciated!!!
