Having outlined a general set of symbols and a template for diagraming, we must now define and illustrate a few ways of classifying kin appropriate to anthropological analysis. Emic and etic ways of classifying kin may differ substantially as demonstrated in the previous discussion of how different cultures distinguish consanguineal from affinal kin. At this point the definitions and distinctions you will view are merely intended to provide an general overview of concepts that will be explained and illustrated more fully as you proceed though the subsequent sections. The first distinction we shall make is between lineal kin and collateral kin.
Lineal kin are either the direct ancestors or descendants of a particular Ego.
They can be pictured as side branches off of the main trunk that links a person to his ancestry and progeny.
