Root compound
MORPHOLOGY: compound whose head is not deverbal or whose non-head does 
not have the function of argument of the verb from which the head is derived.
 EXAMPLE: English compounds such as housewife, blackbird, overcoat, 
rattlesnake, well-formed, off-white, overlook, and so on do not have a 
deverbal head, and therefore can be called root compounds. A compound such as 
truck driver on the other hand has a deverbal head and the non-head is 
an argument of the embedded verb drive. The distinction between root 
compounds and synthetic compounds has played a major role in theoretical 
discussions since the late seventies. Another term for root compound is 
primary compound.  Synthetic compound.
