What are the six words?

g.
who, after lo these many years of desultory attention, knows of only

Quick. Nicely done. Did you happen to know this already?

Here's one that's a little tougher:

Three common 8 letter words. All three are adjectives having to do
with the same broad category of biological necessity. All three begin
with the same letter. Two begin with the same two letter sequence.
All three end with the same two letter sequence. Two end with the
same three letter sequence. There is one repeated letter.

giles.
it might take a while but given all those hints anyone with ancestors
should be able to get this one.
