On the other hand, repeated (continuous) morphemes appear in many languages. In Gk. σοφῶν ảδελφῶν ‘of wise brothers’, we have a continuous morpheme ῶν ‘genitive plural’ about which the special statement must be made that it occurs twice in this phrase. We might say: if ῶν occurs after ảδελφ-, and if σοφ- occurs before, then ῶν will also occur after σοφ-; i.e. noun and adjective agree as to gender, number, and case. However, since the two occurrences of ῶν always appear together and are always identically replaced, as in σοφῷ ảδελφῷ ‘to a wise brother’, we might say alternatively: there is a morpheme … ῶν … ῶν which occurs in σοφ- ảδελφ-, and in other adjective-noun sequences; similarly, there is a morpheme …ῷ … ῷ, etc. When we say this, no special statement is needed about the concurrence of the two ῶν forms: they occur together because they are parts of one morpheme.
