Conjugation Rules For 'Past Tense Informal Verbs' Japanese

Common to both English and Japanese sentences are a subject, verb, and an object.

In Japanese, however, the order of these is different than an English sentence. In English, the order is:

subject, verb, object,

whereas in Japanese, it is:

subject, object verb.

In Japanese, the verb is written at the end of the sentence.



Look at this example simple sentence.

English - I drink wine.
Japanese - I wine drink - wastashi wa wain o nomu

Meaning: wastashi wa -I, wain - wine, nomu - drink
o is particle wo, usually just written as o.

Although it appears odd, this is how a sentence is written in Japanese; with the subject at the beginning and the verb at the end.


Also in Japanese writing, the verbs can be informal or formal. Informal is used when speaking with someone you know, whereas, formal is used in a formal setting, like when meeting someone for the first time.

When conjugating verbs, there are both informal and formal verb tenses. Additionally, there are more than a dozen different verb tenses in Japanese writing. For this verb lesson, we will learn about conjugating verbs to 'past tense informal'. As well, we will learn about particles in Japanese sentences, as they are important to verbs, and to the sentence topic/subject.

Changing Present Tense Verbs To Past Tense:

To change them to past tense informal:

Change the ending letter or letters as shown;

ku-becomes ita,
ru, u, tsu becomes-tta,
mu, nu, bu becomes-nda,
su becomes-shita,
gu becomes-ida.
iru or eru (remove the ru) becomes - ta
To make a present tense verb into a past tense verb you simply change the verb ending.

JAPANESE VERBS with EXAMPLE SENTENCES

Present Tense to Past Tense Informal

Verb: to walk
Present tense aruku Past tense informal: aruita

Example Sentence with verb aruku in Japanese:

English Present Tense: I walk,
Japanese Present Tense: Watashi wa aruku,
Japanese Past Tense Informal: I walked yesteday - Watashi wa kino o aruita.


As you can see from our examples, verbs are written at the end of the sentence in Japanese. As well, the subject of the sentence is followed by a 'particle' like 'wa'. Wa is used to identify the 'topic/subject' in a sentence. For our sentences; I (watashi) is the subject.

Also, the object of the verb is followed by a particle like 'wo', pronounced and usually written as 'o'.

In this past tense example: watashi wa kino o aruita, the word kino (yesterday) is the direct object of the verb 'walk'; therefore, the particle 'o' is placed after it.

In this present tense example, watashi wa aruku, the particle 'o', is not needed because, the word I(watashi), is both the subject/topic of the sentence and the object of the verb. In a Japanese sentence, you do not put put 'wa', next to 'o'. Particles like 'wa', 'o', must follow a word, not another particle. To Learn About Japanese particles
