Assumption:

Argument:

1. adjectives are inflected for number

2. no evidence that dual is excluded from ②

3. Therefore adjectives inflect for dual

Extra-assumption:

Argument:

1. adjectives have the same inflections as nouns

   • ? It only means that they had no distinct inflections of their own; not that they necessarily followed the inflections of nouns to a tee.

2. dual on -t was like partitive plural, plural on -u was like general plural

3. adjective agrees with nouns in partitive plural on general plural

   • nótime eldali, ondolisse morne, not nótimáli, mornali

4. Therefore adjectives agree with nouns in dual on -u.
