Create a printable conjugation chart for godan and ichidan verbs
To create a printable conjugation chart for Japanese godan (五段) and ichidan (一段) verbs, the main points to cover include the conjugation forms common to both, with emphasis on the vowel changes for godan verbs and the stem-based changes for ichidan verbs.
Understanding Godan and Ichidan Verb Groups
Before diving deeper into the conjugation forms, it’s helpful to understand the fundamental difference between godan and ichidan verbs:
- Godan verbs are also called “five-step” verbs because their stem changes through all five vowel sounds (a, i, u, e, o) depending on the conjugation. These verbs typically end with a consonant + う kana (e.g., 書く, 飲む, 話す).
- Ichidan verbs are known as “one-step” verbs because they conjugate by dropping the final る and adding a suffix without stem vowel changes. Many ichidan verbs end with いる or える (e.g., 食べる, 見る).
This distinction affects conjugation patterns significantly and is the basis for creating an effective conjugation chart.

Deeper Explanation of Key Conjugation Patterns
Godan verbs:
The final syllable of the verb stem shifts among the five vowel rows (a, i, u, e, o) to produce different forms:
- Negative (ない-form): Change the final u-sound to a-sound + ない → 書く → 書かない
- Polite form (ます-form): Change final u-sound to i-sound + ます → 書く → 書きます
- て-form: Substitute last syllable’s u-sound with e-form + て (with exceptions) → 書く → 書いて
- Volitional: Change final u-sound to o-sound + う → 書く → 書こう
This vowel-shifting is why these verbs are termed “five-step”—they essentially use all five vowel rows in conjugation.
Ichidan verbs:
Simpler and more predictable, ichidan verbs conjugate by simply dropping る and attaching the suffix:
- Negative: Drop る + ない → 食べる → 食べない
- Polite form: Drop る + ます → 食べる → 食べます
- て-form: Drop る + て → 食べる → 食べて
- Volitional: Drop る + よう → 食べる → 食べよう
Because the stem remains constant, ichidan verbs are easier to conjugate, making them a good starting point for learners.
Common Pitfalls with Godan and Ichidan Verb Conjugation
- Misidentifying verb group: Some verbs ending in える or いる are godan verbs, not ichidan. For example, 帰る (かえる, to return) is godan despite ending in る. Incorrectly conjugating such verbs as ichidan leads to errors.
- Te-form exceptions: Godan verbs have irregular て-form changes. For instance, 話す → 話して, 死ぬ → 死んで, 泳ぐ → 泳いで. These need to be memorized or referenced carefully.
- Potential form ambiguity: Ichidan verbs form potential with 食べられる, but colloquially sometimes shorten to 食べれる, which is grammatically incorrect in formal situations.
- Polite vs. dictionary form confusion: It’s easy to mix polite ます-form endings with dictionary forms, especially with godan verbs since the stem changes visibly.
Step-by-Step Guidance for Using the Chart to Conjugate Verbs
- Identify the verb group: Determine whether the verb is godan or ichidan.
- Locate the base stem:
- Godan stem includes the consonant plus the final kana that changes vowel.
- Ichidan stem is the verb minus る.
- Apply the vowel change or suffix: According to the conjugation required (e.g., negative, past, potential), change the last kana for godan or add suffix for ichidan.
- Check for exceptions: Especially for the て-form in godan verbs, consider irregular conjugations.
- Use the conjugation chart as a reference: Confirm that the conjugated form matches the examples in the chart.
Practical Tips for Printing and Using the Chart
- Print in color: Highlight the vowel changes for godan verbs (a, i, u, e, o) in different colors to visualize the pattern easily.
- Add romaji readings: Including romaji alongside kanji/kana helps reinforce pronunciation.
- Keep a pocket-size version: Small laminated cards with the conjugation chart can be convenient for on-the-go review.
- Create verb-specific flashcards: Using the chart’s structure, make personalized cards for your most common verbs to deepen retention.
FAQ on Godan and Ichidan Verb Conjugation Charts
Q: Can a single chart work for irregular verbs too?
A: Irregular verbs like する (to do) and 来る (to come) do not follow godan or ichidan patterns and need separate charts.
Q: Are all ichidan verbs predictable from their endings?
A: Many ichidan verbs end with いる or える, but exceptions exist; it’s best to double-check with a dictionary or trusted source.
Q: Why is the potential form often longer for ichidan verbs?
A: Ichidan verbs generally add られる for potential, making them longer. However, casual speech sometimes shortens this, which is not recommended for formal writing.
