In the exercises A3, A4, and A5, we are learning a helping verb “oku/okimasu” which is not “okiru/okimasu”, though the Masu-forms are the same “okimasu”. The verb “Oku/Okimasu” describes action to put something onto somewhere, shown as below.
– Te’eburu ni Koppu o Okimashita. ((I) put a glass cup on the table.)
But once this verb has become a helping verb in the form of “[Vt-te] oki masu.”, the original meaning is weakened, instead, it adds some meaning to the verb in Te-form.
Either the original or helping verb, the conjugation patterns of “oku/okimasu”are as follows.
– Dictionary form = oku, Masu-form = oki masu
– Nai-form = okanai
– Te-form = oite, Ta-form = oita
– Potential form = okeru
Since the Nai-form is “o<ka>nai”, this verb’s conjugation pattern is “Group 1 – K”.
We have learned other helping verbs “-iru” and “-aru” recently. So, look at three sentences below. Each of them uses “[V-te] iru”, “[V-te] aru”, and “[V-te] oku” in this order.
1. Kaban ni Denshi-Jisho ga Haitte i masu. (There has been an electric dictionary in the bag.)
2. Kaban ni Denshi-Jisho ga Irete ari masu. (An electric dictionary has been put in a bag.)
3. Kaban ni Denshi-Jisho o Irete oki masu. (I am going to put an electric dictionary in a bag.)
The sentence 1 and 2 express the current situation, but the sentence 3 expresses a will to do in near future. This difference comes from the original meanings, or nature of the verbs.
– “Iru/Imasu” and “Aru/Arimasu” are verbs to describe an existence. They are stative verbs
– “Oku/Okimasu” is a verb to describe action that can be done in short period of time. This is a kind of momentary verb whose present tense is actually future tense and/or a strong will to do it in near future.
Although I don’t want to confuse you readers, other comparisons would be like below;
1. Jisho<ga>, Hairu=intransitive verb, iru=intransitive verb
2. Jisho<ga> Ireru=transitive verb, aru=intransitive verb
3. Jisho<o> Ireru=transitive verb, oku=transitive verb
Do you remember that I wrote recently;
4. Shinkansen no Kippu ga Yoyaku-shite arimasu.
5. Shinkansen no Kippu o Yoyaku-shite arimasu.
The sentence 4 is okay, but 5 should not be written in a textbook. By avoiding 5, the comparison between “[V-te] aru” and “[V-te] oku” could be easier for the learners.
2′. Noun<ga> [Vt-te] + aru=intransitive verb
3′. Noun<o> [Vt-te]+ oku=transitive verb
For the sentence 2′, if you think the noun is related to “aru” which is an intransitive verb, the particle for the noun would be “ga”. As for 3′, thinking the noun is related to “oku” which is a transitive verb, the particle for the noun would be “o”.
Now, look at the sentence for today;
6. Ichigakki ga Hajimaru Mae ni, Kyoukasho o Katte okimasu.
(Before the first semester starts, I will buy the textbooks.)
In A3, we are learning “[V-te] okimasu” which appears in the last phrase of the sentence 6. As for the first phrase “[Subject] ga [V-dic] Mae ni” is also important. We actually have learned this construction at exercise A4 in the section 18. Look at carefully this phrase;
In a sentence of [Dependent Phrase], [Main Phrase].,
[Dependent Phrase],
= [Subject] ga [V-dic] Mae ni,
– “Subject” is not the subject of the entire sentence, but the subject inside the dependent phrase. Usually, the subject of the sentence is the subject of Main Phrase.
– “ga” is the subject marker. Don’t think that the sentence always starts with a word with “wa”. This dependent phrase is a conditional phrase that functions as an adverbial. In order to make such a phrase state the condition clearly about What/Who does What, the phrase need to specify the subject inside the phrase. “ga” is the subject marker when the subject needs to be specified.
– [V-dic] means a verb in dictionary form which ends with “-u”. When a verb modifies a noun, the verb would be one of Dictionary form, Nai-form, Ta-form, or V+nakatta. Since the sentence 6 is talking about a will what the speaker is going to do near future, Dictionary form is the only applicable to the sentence 6.
– “Mae” is a noun unlike “Before” in English is preposition and/or conjunction. Therefore, it usually needs particle (postposition) behind. In the case of the sentence 6, the particle is “ni”.
– “ni” is a particle whose basic function is to indicate the target that action of a verb is heading to. Any words or phrases that are attached “ni” at the end work as adverbial to the verb behind. Therefore, when you hear a word with “ni”, you can anticipate a verb is coming soon. In the case of the sentence 6, the {dependent phrase} works as adverbial phrase to [the main phrase].
6. { Ichigakki ga Hajimaru Mae ni }, [Kyoukasho o Katte okimasu].
Since “Made ni” is used in the exercise B4 which is corresponding to A3, practice and remember the following two sentences;
7. Natsuyasumi, Jikkan ni Kaeru Mae ni, Omiyage o Katte okimasu.
(Before I return to my parents’ house in summer break, I will buy souvenir.)
8. Raishuu no Jugyou Made ni, Kyoukasho no Go-juu Roku Pe’eji kara Roku-juu San Pe’eji o Yonde oite kudasai.
(By the class in next week, read your textbook from page 56 to 63.)
Sentence construction is; [Noun] Made ni, [V-te] + oite*+ kudasai.
* “oite” is the Te-form of “oku/okimasu”
At last of this post, here is an important thing. Both “[V1] Mae ni, [V2-te] okimasu.” and “[Noun] Made ni [V-te] okimasu” are expression to say a preparation will be taken beforehand.
