Unlocking the Nuances of Japanese Habitual Verbs: Understanding the “-masu“ and “-suru“ Systems110

Japanese, a language renowned for its politeness levels and intricate grammatical structures, presents unique challenges for learners, particularly when it comes to expressing habitual actions. While English utilizes simple verb tenses like "I usually go" or "I often eat," Japanese employs a more nuanced system involving auxiliary verbs, sentence structure, and specific verb conjugations to convey the frequency and habitual nature of an action. This system largely revolves around the versatile "-masu" and "-suru" verb conjugations, each with its own set of subtleties.

The core of expressing habitual actions in Japanese lies in the skillful manipulation of auxiliary verbs. While the simple past tense (past form of -masu verbs) can sometimes imply habitual actions in the context, it’s not the primary means of expressing habituality. Instead, the auxiliary verbs 「する」(suru – to do) and its conjugations, along with the more common "-masu" verb conjugations, play a crucial role. The choice between these two depends largely on the main verb itself – whether it's a verb ending in "-suru" or another verb conjugation.

Let's examine the "-masu" system first. The most straightforward way to indicate habitual actions with "-masu" verbs is through the use of the auxiliary verb 「いつも」(itsumo – always) or 「よく」(yoku – often/frequently). These adverbs precede the verb in its plain form (the form before adding "-masu"). For example:
私はいつもコーヒーを飲みます。(Watashi wa itsumo kōhī o nomimasu.) – I always drink coffee.
彼はよく映画を見ます。(Kare wa yoku eiga o mimasu.) – He often watches movies.

However, simply adding these adverbs doesn't fully capture the nuances of habituality. For a more ingrained habit, one might use expressions like 「毎朝」(maiasa – every morning), 「毎日」(mainichi – every day), 「毎週」(maishū – every week), or 「毎年」(maitoshi – every year) to specify the frequency.

The "-suru" system, on the other hand, presents a slightly different picture. Since "suru" itself means "to do," it's often used as an auxiliary verb to create compound verbs. Habitual actions with "-suru" verbs are typically expressed in a similar manner to "-masu" verbs, using adverbs like 「いつも」(itsumo) and 「よく」(yoku) before the verb.
私はいつも散歩をします。(Watashi wa itsumo sanpo o shimasu.) – I always take a walk. (散歩する - sanpo suru - to take a walk)
彼女はよく料理をします。(Kanojo wa yoku ryōri o shimasu.) – She often cooks. (料理する - ryōri suru - to cook)

Beyond simple adverbs, Japanese employs other grammatical structures to emphasize the habitual nature of an action. The te-form (て形 - te-kei) followed by auxiliary verbs like 「いる」(iru – to be/exist) or 「いる」(iru – to be/exist) can effectively convey habitual actions. This construction emphasizes the continuous or ongoing nature of the habit.
毎日、本を読んでいます。(Mainichi, hon o yon-de imasu.) – I am always reading books. (The -te form "yon-de" emphasizes the continuous nature.)
週末はいつも家で映画を見ています。(Shūmatsu wa itsumo ie de eiga o mi-te imasu.) – I’m always watching movies at home on weekends.

Another subtle distinction lies in the use of potential forms (potential verbs). While not directly expressing habituality, they can subtly hint at a frequently attempted, though not always successful, action. For example, 「よく泳げます」 (yoku oyogerimasu – I can swim well/I often swim) suggests a habitual activity more strongly than simply stating 「泳げます」(oyogerimasu – I can swim).

The nuances of expressing habitual actions in Japanese extend beyond simple verb conjugations and auxiliary verbs. Context plays a crucial role. Sometimes, even the plain form of a verb, without any auxiliary verbs or adverbs, can imply habituality, depending on the surrounding sentences and overall conversational flow. Mastering the art of expressing habitual actions in Japanese requires a deep understanding of these intricate grammatical structures, along with a keen awareness of context and conversational nuance.

In conclusion, while seemingly simple at first glance, expressing habitual actions in Japanese demands a careful consideration of verb conjugation, auxiliary verbs, adverbs of frequency, and contextual cues. The "-masu" and "-suru" systems, though seemingly straightforward individually, reveal a complex interplay when used to describe habitual activities. Through diligent study and practice, learners can unlock the richness and subtlety of expressing habitual actions in this fascinating language.
