Japanese Revelations {How to conjugate う-verbs to other basic forms}

At first, the various verbs of the Japanese language seem daunting. However, stick with learning it, and you'll find out that, though there are two kinds, and both conjugate differently, the る-verbs are super simple to change to different forms, and the う-verbs are a bit trickier, but aren't as difficult as they might seem at first, possibly because a fair amount of verbs that end in る are actually う-verbs. There is a trick to being able to tell most of the time what kind of verb a verb is, though.
If the verb ends in an ～ある, ～うる, or ～おる sound (meaning the second-to-last syllable is from the あ, う, or お column), the verb is most likely a う-verb.
If the verb ends in ～える or ～いる, and the second-to-last ～え or ～い sound isn't part of the kanji, it's most likely a る-verb. On that note, let's look at う-verbs! ^^

First of all, there's a helpful little chart for the different (basic) forms of う-verbs. Study this, guys - it's absolute genius. XD

～あ*	| negative form: add ～ない
～い	| ます form: add ～ます
～う	| Dictionary form: this is what you start out with.
～え	| Command form: leave it as-is, with an え-sound at the end | 'If'-form: just add ～ば)
～お	| Volitional form (meaning "let's ____): add a ～う to the end

* If the verb ends with a う (like in 買う － to buy) change the う to a わ and then add ～ない (買う → 買わない).

The ～'s in front of the あ, い, う, え, and お mean change the syllable that ends in a u-sound (in the う column, such as う, く, ぐ, す, つ, ぬ, ぶ, む, and る, as う-verbs can end in those sounds only) to a syllable from the same consonant family. For example...

う→わ・い・え・お
く→か・き・け・こ
ぐ→が・ぎ・げ・ご
す→さ・し・せ・そ
つ→た・ち・て・と
ぬ→な・に・ね・の
ぶ→ば・び・べ・ぼ
む→ま・み・め・も
る→ ら・り・れ・ろ
（The ・ symbol is the Japanese equivalent of a slash)

On a brighter note, hopefully this all makes sense now. ^^ I used a verb with each possible syllable at the end for a reason~

Have fun learning Japanese! ^u^

PS:
WARNING! 行く （いく） is NOT a う-verb! It's an irregular verb, so pay attention to its conjugations and its different forms!!
