The existence of a 2nd person dual pronoun seems to always imply that of a 1st person dual, whether with or without the inclusive-exclusive distinction, and/or a 3rd person dual.
Standardized
IF there is a dual for 2nd person pronoun, THEN there is a dual for either 1st or a 3rd person or both. There will be never a dual limited to 2nd person.
1. Cf. Humboldt’s claim #568: If 2nd and 3rd Person differentiates a Dual, so does (with more than chance frequency) 1st (but not vice versa); see also Plank’s generalizations ##1136, 1137. 2. Cf. #1951.
