Question

define base of stem ​

Answer 1

This means that any root or any stem can be termed a base, but the set of bases is not exhausted by the union of the set of roots and the set of stems: a derivationally analysable form to which derivational affixes are added can only be referred to as a base

Answer 2

Answer:

A base is any form to which affixes of any kind can be added. This means that any root or any stem can be termed a base, but the set of bases is not exhausted by the union of the set of roots and the set of stems: a derivationally analysable form to which derivational affixes are added can only be referred to as a base. That is, ‘touchable’ can act as a base for prefixation to give ‘untouchable’, but in this process ‘touchable’ could not be referred to as a root because it is analysable in terms of derivational morphology, nor as a stem since it is not the adding of inflectional affixes which is in question.
