What exactly does -nasai do?
I thought I wouldn't have any questions left for today, Yappari, I was wrong! :) More from the newbie-front!
Okay, so when I learnt 'yasumi' (vacation, time off) today, I immediately had to think of 'oyasuminasai' (good night), which, stripped down, begets us:
So, assuming the 'o' functions like a built-in honorary prefix, as it were (or it is something else, but it's not relevant for my point), I got to wonder what exactly -nasai does. From what I can tell, often it feels like it functions as a kind of 'assuaged Imperative' (for lack of a better term); like:
Suwarinasai! -> (Please) have a seat!
The 'suwarinasai' form does not appear in the verb conjugator:
Yet it exists; like:
Shukudai o shinasai! -> (Please) do your homework!
And this 'softened' Imperative (surprisingly, almost) seems to work on 'oyasuminasai' too, so as to form something like: "(Please) take the off-time!" So, I pushed my luck, and tried it on 'okaerinasai' (in response to tadaima!) too:
And, indeed, kaeri appears to be "return, coming back." So far so good. But the Imperative sense, however softened, seems lost here (or manifests itself in a way invisible to me). So, my simple question is, what does -nasai do precisely? My gut tells me I can't be too far off, but I need just this small nudge, it seems, to get me fully on-track. Either that, or I derailed myself completely. :)
Arigato gozaimasu!Wozitoya-san, thank you for explaing the verb conjugation rules.
Okay, minna-san, let me see if I can fit this into a single rule my brain can grasp, and which will allow for irregular verb as well. What if I break of the -masu form of each verb, and replace it with -nasai, would that work?
kuru -> ki-masu -> ki-nasai
suru -> shi-masu -> shi-nasai
wakaru -> wakari-masu -> wakari-nasai
iu -> ii-masu -> ii-nasai
yomu -> yomi-masu -> yomi-nasai
miru -> mi-masu -> mi-nasai
Seems to work. Would this be a valid way to go about it?
Thanks!Well, seems it also works on taberu (not having '-imasu'):
taberu -> tabe-masu -> tabe-nasai
So, I'm just assuming I'll be pretty safe with the '-masu' rule.
