寄付 and 譲る: supporting an activity and passing an item on
Compare donating books to a library with passing a watch to a grandchild. Read the overlap between transfer and support without limiting donations to money.
Support an activity through 寄付
寄付, read きふ, means donation or contribution. 使わない本を地域の図書室に寄付した。 says that unused books were donated to the local library.
Books are the donated object and the library the recipient. Goods can be donated; this scene focuses on supporting the library through the provision.
Pass the item on through 譲る
For the transfer side of this comparison, 譲る, read ゆずる, means pass an item on. 祖父は大切にしていた時計を孫に譲った。 says that the grandfather passed his cherished watch on to the grandchild.
This focuses on passing the object to another person. A transfer may also support an activity as a donation, so the words do not always require mutually exclusive actions.
Read the intended use of the donation
祭りで集まった寄付は修理費に使われる。 says that donations collected at the festival will be used for repair costs. Distinguish their collection from their future use.
Read the books and repair-fund examples together. Check the object, recipient, and support purpose without inventing procedures or amounts absent from the sentences.
Must 寄付 always concern money?
Show the answer and why
No. Books can be donated, as in the library example. Read what is provided, to whom, and for what purpose in context.
