さしあげる・くださる・いただく
Giving and receiving in humble / honorific formsmachine translation
FormationSame structures as あげる・くれる・もらう, used when giving and receiving with superiors
When giving and receiving with superiors (teachers, bosses, customers), the trio あげる・くれる・もらう switches to polite forms: さしあげる (humble — I give/present to a superior), くださる (honorific — a superior gives to me), いただく (humble — I receive from a superior). The sentence structures and particles stay the same as with the plain set.
Note that くださる conjugates irregularly in the ます-form: くださいます (not くださります). In fact, you've been using relatives of these words all along: the ください in 〜てください from N5 is the imperative form of くださる, and the いただきます said before meals literally means "I humbly receive."
In the opposite, downward direction — giving to children, animals, or plants — traditional Japanese uses やる instead of あげる: 犬にえさをやる (feed the dog) — though nowadays many people just use あげる as the gentler option. This whole set belongs to the honorifics system you'll study in full in the Keigo chapter.
