The Past Is the Past: Japanese Adjectives in the Past Tense
Here we go!
Japanese Adjective Review
Before we begin, let’s review some common adjectives in the present tense. In Japanese, there are two types of adjectives: i–adjectives and na-adjectives. I-adjectives end in the hiragana character い (i), and na–adjectives end in な (na). The first table below is a list of i-adjectives, and the second is for na–adjectives.
|ひま（な）||hima (na)||free (not busy)|
|元気（な）||genki (na)||healthy/energetic/in good spirits|
Now that we’ve familiarized ourselves with a few common i- and na-adjectives, let’s create a few sentences!
Kotoshi no hana wa utsukushii!
The flowers this year are beautiful!
Ano gake wa kiken desu!
That cliff is dangerous!
I-Adjectives in the Past Tense
In order to conjugate an i-adjective into the past tense, you simply remove the last character い and replace it with かった (katta).
If you want to make the sentence formal, you add です (desu) to the end of かった.
The table below shows how to conjugate i-adjectives into the past tense. The word in parenthesis is only added if you want to make the sentence formal.
I-ADJECTIVES (PAST TENSE)
|美し||utsukushi||beautiful ➝ was beautiful|
|忙し||isogashi||busy ➝ was busy|
|早||haya||early/fast ➝ was early/fast|
|新し||atarashi||new ➝ was new|
|短||mijika||short ➝ was short|
Now that we know how to conjugate i–adjectives into the past tense, let’s create some sentences! The sentences with です attached to the end are formal and those without are casual.
Example sentences (i–adjectives):
Haru no hana wa utsukushikatta desu.
The flowers in spring were beautiful.
Watashi wa senshuu isogashikatta.
I was busy last week.
Kare wa marason de hayakatta desu.
He was fast at the marathon.
Kanojo no burausu wa atarashikatta.
Her blouse was new.
Ken-san wa wakai toki, ashi ga mijikakatta desu.
When Ken was young, his legs were short.
Na-Adjectives in the Past Tense
In order to conjugate na–adjectives into the past tense, you simply leave out the な and add either だった (datta) for casual sentences, or でした (deshita) for formal sentences.
The table below shows how to conjugate na-adjectives into the past tense. The word before the slash (だった) is used for casual occasions, and the word after the slash (でした) is used for formal occasions.
NA-ADJECTIVES (PAST TENSE)
|危険 ➝ 危険だった／でした||kiken ➝ kiken datta / deshita||dangerous ➝ was dangerous|
|嫌い ➝ 嫌いだった／でした||kirai ➝ kirai datta / deshita||hated/disliked ➝ was hated/disliked|
|ひま ➝ ひまだった／でした||hima ➝ hima datta / deshita||free (not busy) ➝ was free (not busy)|
|大切 ➝ 大切だった／でした||taisetsu ➝ taisetsu datta / deshita||important ➝ was important|
|元気 ➝ 元気だった／でした||genki ➝ genki datta / deshita||healthy/energetic/in good spirits ➝ was healthy/energetic/in good spirits|
Now that we know how to conjugate na–adjectives into the past tense, let’s create some sample sentences!
Example sentences (na–adjectives in the past tense):
Kinou yuki de douro ga kiken deshita.
Yesterday, due to the snow, the roads were dangerous.
Watashi wa kodomo no toki, burokkorii ga kirai datta.
When I was a child, I hated broccoli.
Koukousei no toki wa takusan hima deshita.
In my high school days, I had lots of free time.
Kare wa shounen no toki, jitensha ga taisetsu datta.
When he was a boy, his bicycle was important to him.
Obaasan wa yon-juu nen mae genki deshita.
My grandmother was energetic 40 years ago.
With i-adjectives, you simply remove the い at the end of the word and replace it with かった. If you want to make the sentence formal, you add です after かった. Take a look at the differences in the table below.
With na-adjectives, you leave out the な and add だった instead. For formal sentences, you use でした instead of だった. The differences are below.
|危険だったkiken datta||危険でしたkiken deshita|
Now that you have a new grammar point under your belt, it’s time to get out there and practice! Talk with your Japanese speaking partner about the way things used to be in your pasts. Make sure to utilize both i-adjectives and na–adjectives so that you get used to the differences between the two.
Remember, it’s impossible to master a new language if you don’t practice! And if you practice every day, your skills will sharpen even quicker! Therefore, let’s make it a goal in 2020 to practice Japanese every day!
