Specific morphemes may have (1) any number of semes of type 1a, e.g. 'boy', (2) combinations of 1a and 1b, e.g. 'slop', and (3) either of the above, plus a 'clustering' of associated semes of type 2. Semes of type 2 are generally not described as the 'meaning' of a specific morpheme, but are associated with a particular morpheme or combination of morphemes in a specific paradigmatic series.

The meaning of a particular morpheme consists of (1) the linguisememe (or linguisememes, if one wishes to distinguish between classes of linguisememes), and (2) the ethnosememe (or ethnosememes) symbolized by or associated with the form. The meaning of the form 'boy' may be described in terms of (1) the linguisememe of 'noun' and (2) the ethnosememe, consisting of the various related ethnosemes occurring with this word in its different contexts, e.g. (1) 'Oh boy!', (2) 'a bright young boy', and (3) 'a good old boy', and (4) 'boy', used as the name for a servant.
