=Godan Verbs=
Japanese Verbs are very easy to put together, especially the {{ruby-ja|五段|ごだん}}&nbsp; (Godan) ones. Remember the order of vowels from the [[Japanese Roman Character Pronunciation Guide]]? Just to refresh your memory, they go あ, い, う, え, お. There are 5 sounds obviously, and it is this number that the conjugation gets its name from. {{ruby-ja|五|ご}}&nbsp;(Go) means 5, and {{ruby-ja|段|だん}}&nbsp; (dan) means stage.

Japanese verbs have a different style of conjugation completely than our verbs. They conjugate to express not only time, but certain feelings we would express using more words. {{ruby-ja|五段|ごだん}}&nbsp; (Godan) verbs include all verbs that do not end with -iru or -eru sound (the 'i' and 'e' can be preceded by a consonantal sound) as well as some that actually do end with them but are not する and くる (suru or kuru). Most verbs ending with the letters -いる and -える (-iru and -eru) are ichidan verbs (one stage), with some exceptions, while する and くる (suru and kuru) are the most common irregular verbs in Japanese.

The conjugation follows this pattern:

*あ(a)	negative form
*い(I)	infinitive form
*う(U)	dictionary form
*え(E)	conditional form
*お(O)	"let's" or "volitional" form

In order to show you how this works, let's select one {{ruby-ja|五段|ごだん}}&nbsp; (Godan) verb: {{ruby-ja|行く|いく}}&nbsp; (iku), which means "to go" and follow it through a full five conjugations. Conjugation deals only with changing the vowel at the end of the original dictionary form verb, and sometimes adding a suffix. The Dictionary form is so called because this is the way you will find a verb in the dictionary, it will always end with う(u) in this form without exception.

===Negative===
行く|いく (iku), when changed to negative, must first take the vowel with which this form is associated as its last vowel. Since the negative form is associated with あ(a), {{ruby-ja|行く|いく}}&nbsp; (iku) drops the う(u) from its dictionary form past and becomes {{ruby-ja|行|い}}か (Ika). In a case where you have a word like Au, (to meet) you will note that this would turn into "aa-nai" in the negative under these rules. For such silliness an escape is provided. the "a" you add on in the end becomes "wa" thus, "Awa-nai". Remebering that the raw verb of Iku begins in the dictionary form (u-form) is tantamount to remembering that you do not add the vowel in conjugation, you replace it. Iku becomes Ika. The next step is to add the negative suffix to the word Ika. This suffix is "nai." The negative form of Iku is Ikanai: "not go."

===Infinitive===
Infinitive form is the form onto which you may add either other verbs, other levels of honour, or both. It is also the base form from which the standard "desu-masu" Japanese is spoken. This is the kind of Japanese this course will teach you.

The ininitive form is almost a stand-alone form. You can speak using only what is provided in this conjugation almost without need for others in very basic Japanese. In order to change the dictionary form to infinitive form, we drop the "u" and add "i", making our "Iku" become "Iki". Onto the new-made "Iki" we affix "-masu" as a suffix, making the complete word Ikimasu: "go".

As I said, this form is pretty stand-alone, and onto the positive for this form, you may add another suffix to make it negative. Change the "-masu" to "-masen" and you have your negative: Ikimasen, meaning "not go".

===Dictionary===
As said previously, dictionary form is the standardized form for finding verbs in dictionaries. This is the form that has all verbs, regardless of conjugation schemes, with a "u" at the end invariably.

===Imperative/Conditional===
The E form is used in giving commands, suggestions, or making hypothetical statements. There is occasionally no suffix to this form. To change Iku to the imperative, drop the "u" and add "e." The imperative form of "Iku" is "Ike." Do not say 'ike' （いけ！） to anyone because it is slightly vulgar and is offensive. When you add the suffix "-ba" to this form, it becomes a true conditional. "Ikeba" could variously be translated to "why don't you go?" or "what if you went?" You might also hear the phrase "ikeba wakaru." Wakaru is dictionary form of the verb to know or understand. This phrase therefore means "IF (you) went, (you'd) understand."

===Volitional===
The O form is the one that is confusing to most English speakers. It is the "let's" form. If I were to change Iku to the volitional form, I drop the "u" and add "ou." The suffix in this case is not easy to notice, as it is a "u." This simply extends the o sound. Iku becomes Ikou: "let's go." The word Ikimasu may also be conjugated in this form, simply converting the "-masu" ending to a "-mashou," making the whole word "Ikimashou."
