interdigitate

interdigitate (in-ter-DIJ-i-tayt) - n., to become folded or interlaced together like the fingers of clasped hands; to intermingle, to alternately present items from one group and then another.


Things can be interdigitated by someone or can interdigitate themselves -- though that figurative extension seems to be used more as a transitive verb. Coined around 1850 from Latin roots inter-, between/in the midst of + digitus, finger.
