First off, we will start our Japanese Conjugation from Japanese verbs or どうし! | Illustration by Irasutoya

Our adventure begins deep within the Verb Jungle, where three distinct groups of verbs await. Think of this as selecting your character class in a video game, with each group presenting its unique set of challenges and rules.

Group 1 (u-verbs)

These verbs end in -u and can be likened to the rogues of the jungle. Transforming them is as simple as swapping -u with -i for the present affirmative form or -imasen for the present negative form. For the past tense, it’s a matter of replacing -u with -ta. However, for the past tense, don’t forget to change the -u to -i first!

飲む・のむ・nomu – to drink

Affirmative Polite FormNegative Polite Form
Present飲みます・のみます・nomimasu飲みません・のみません・ nomimasen
Past飲みました・のみました・nomimashita
飲みませんでした・のみませんでした・ nomimasen deshita

So, when you wish to say, “I drink,” it becomes “のみます・nomimasu” If you’d like to express, “I don’t drink,” it’s as easy as saying “のみません・nomimasen.” To recount that delightful drink you savored yesterday, simply utter “のみました・nomimashita.” For more examples, you can check this blog post to ease your learning! 

Group 2 (ru-verbs)

These verbs, often ending in -ru, can be seen as the knights of the Verb Jungle. Conjugating them involves wielding your conjugation sword and removing the -ru, then adding -masu for the present affirmative form, -masen for the present negative form, and -mashita for the past tense.

Irregular Verbs

Enter the world of irregular verbs, the mystical wizards of the Verb Jungle. These verbs, like “suru” (to do) and “kuru” (to come), defy the usual rules and have their own unique conjugation patterns that require memorization.

する・suru – to do

Affirmative Polite FormNegative Polite Form
Presentします・shimasuしません・shimasen
Pastしました・shimashita しませんでした・shimasen deshita

来る・くる・kuru – to come

Affirmative Polite FormNegative Polite Form

Past来ました・きました・kimashita来ませんでした・きませんでした・kimasendeshita

Grooving with Adjectives

With the Verb Jungle behind us, let’s groove on the Dancefloor of Descriptions with Japanese adjectives, which come in two distinct styles: i-adjectives and na-adjectives.

i-Adjectives

Picture these adjectives as the life of the party, ending with -i. To get into the adjective groove, simply replace -i with -katta for the past tense or -ku nai for the negative form.

高い・たかい・takai – tall/expensive/high

Affirmative Polite FormNegative Polite Form
Present高いです・たかいです
takai desu
高くありません・たかくありません・takaku arimasen
Past高かったです・たかかったです・takakatta desu高くありませんでした・たかくありませんでした・takaku arimasen deshita

When you want to say, “It’s high,” it becomes “Takai.” But when you recall that it wasn’t so tall, it transforms into “Takakunai.” And if you spent time with a tall friend last night, you reminisce with “Takakatta.”

na-Adjectives

These adjectives prefer to keep things chill and add “na” when they hang out with nouns. Conjugating them is a breeze—just add -datta for the past tense and -ja nai for the negative form.

静かな・しずかな・shizukana – quiet, peaceful

Affirmative Polite FormNegative Polite Form
Present静かなです・しずかなです
shizukana desu
静かじゃないです・しずかじゃないです・shizuka jyanai desu
Past静かだったです・しずかだったです・shizukadatta desu 静かじゃなかったです・しずかじゃなかったです・shizuka jyanakatta desu

So, “It’s quiet” becomes “Shizuka na.” To say it’s not quiet, it’s “Shizuka ja nai,” and when reminiscing about a noisy night, it’s “Shizuka datta.”

Politeness Levels and the Language Duel

In the Land of Politeness, conjugation becomes a refined art form, much like a duel between samurai. Here, there are three levels of politeness, and choosing the right one can be as crucial as striking with precision.

Polite Form (ます – masu)

Imagine this as donning your finest kimono for a royal banquet. It’s used in formal situations, such as speaking with superiors, strangers, or during business transactions. The conjugation follows the standard rules we’ve learned.

食べる・たべる・taberu – to eat

Affirmative Present食べます・たべます・tabemasu
Affirmative Past食べました・たべました・tabemashita
Negative Present食べません・たべません・tabemasen
Negative Past食べませんでした・たべませんでした・tabemasendeshita

Plain Form (だ – da or です – desu)

Picture this as wearing jeans and a T-shirt to meet friends at the local ramen shop. It’s for casual, everyday interactions. For verbs, it uses the dictionary form (the basic form before conjugation). For adjectives, it’s the same as the affirmative form.

食べる・たべる・taberu – to eat

Affirmative Present食べる・たべる・taberu
Affirmative Past食べた・たべた・tabeta
Negative Present食べない・たべない・tabenai
Negative Past食べなかった・たべなかった・tabenakatta

Humble Form (おります・いたします – orimasu/itashimasu)

Imagine donning an elaborate kimono to serve tea to your honored guests. It’s used when showing respect or humility, often in business or customer service. The conjugation has its unique patterns.

For example, instead of saying “I will eat,” you say “飯をいただきます・Meshi o itadakimasu.”

Time Traveling with Tenses and Aspects

Calling the time travelers! Japanese Conjugation rules also depend on when the event happened. | Illustration by Irasutoya

In our linguistic adventure, we’ve discovered that conjugation can also transport us through time, much like a time-traveling explorer. Japanese offers various tenses and aspects to explore.

Present Continuous

To express ongoing actions in the present, add -te iru to the verb stem.

So, “I am eating” becomes “Tabete iru.”

Past Continuous

To express ongoing actions in the past, add -te ita to the verb stem.

“I was eating” becomes “Tabete ita.”

Present Perfect

To express an action completed in the past but still relevant in the present, add -te aru or -te iru to the verb stem.

So, “I have eaten” becomes “Tabete aru.”
