There isn't a widely / singularly accepted term that describes the specific
phenomenon in sign languages of combining a fingerspelled word with a signed
word -- at least not one I can recall from the literature. I suppose someone
somewhere might have included such a term in a paper or article somewhere. Or
maybe we can think of a decent term.
Maybe "lexicalized-affixation." For now I think I'll just use the term "combined
signs" and expect to have to explain that each time I refer to it at the
beginning of a discussion on the topic.
A few signs or parts of signs to look into regarding this topic:
CO-
PRE-
OUT (FIND+[fs]-OUT)
CAT+[fs]-UP
[fs]-GRAND+CHILDREN
[fs]-GRAND+DAUGHTER
[fs]-GRAND+SON
