A more thorough explanation:

Term: Donative
Definition: Donative means related to giving something as a gift or donation. It can also refer to something that is given as a donation. For example, a donative transfer is when someone gives something as a gift, and an advowson donative is a church position that is given as a donation.
Examples:

• She made a donative contribution to the charity.
• The museum received a donative gift from a generous donor.

These examples illustrate the definition of donative as they both involve giving something as a gift or donation.

Both of these actions involve giving something as a gift or donation, which is what donative means.
