Peggy has been using the term “nice” very frequently both as an
expression of her feeling about something and her request for
concurrence. For example, in P99 or P98, after drawing on a piece of
paper, she asked “Nice?” and I agreed.

This evening she brought her bear to the bench of our picnic table and
said, “Nice.” Lifting her bear onto the bench and said “Nice…bear.”
(The pause between the adjective and noun is uncertain.”

“Nice bear” looks like a standard English phrase (as written), but is it?
I believe the anchor of the phrase is the primary thing, “nice” – with the
subsequent term “bear” appearing as the further specification of what
that feeling attaches to.
