Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means presents so if you do presents, you're giving them, making this to give a present or to gift.

贈る is used for the act of giving when it's done with particular thoughtfulness or sincerity — often to express things like gratitude, love, congratulations, or respect. Things you might 贈る include flowers on a birthday, a commemorative item at an event, or even words of thanks. It can also extend to bestowing honors, titles, ranks, or awards, as these are also "gifts" in a sense.

This word has the same reading as 送る (to send), so here's a mnemonic to help you remember it:

If you want to give a present to someone far away, you're going to need to 送る (おくる) it to them. Make sure you pay for tracking!
