को: Beneficiary ~> Recipient

Nouns such as "support" or "benefit" (लाभ/फ़ायदा) will have Beneficiary↝Recipient. This label has been used in the Little Prince annotation for "dedicated to" so there is some precedent. Of course, support and benefit are abstract so one cannot literally receive them, hence Beneficiary.
