The table above  synthezises japanese verb conjugations.

The above table shows an optional way of organizing japanese verb groups and their conjugations.

Why do we need an optional japanese conjugation table?

The main reason is to help japanese language learners learn faster and eliminate vagueness.

I asked many foreigners, including some scholars, the following question:
How many basic conjugations does a japanese verb have ?
I wasn't able to get a straight answer from anyone.
Most people who bothered to answer said something like:

"It's hard to say, because it's hard to say where a japanese conjugation starts and where it ends"

or

"The subjectivity of your question, such as "basic" makes it difficult to answer because who knows what basic refers to?"

or

"Hello, Well, I'm not sure exactly how many basic conjugations there are in Japanese. I guess it's just something people don't really pay attention to, unless they are linguists"

or

"Are the plain negative (-nai) and plain negative past (-nakatta) two different inflections? If not, do you consider "shitagawa" to be a "form" of "shitagau"? It cannot be used by itself, so it is strange to think of "nai" and "nakatta" as separate words if one says "shitagawanai" or "shitagawanakatta." If so, how about -nakereba? And is -nakerebanaranai a single ending or is the -naranai a separate word?"




I knew they wouldn't be able to give me the correct answer. Basically, I only asked to prove a point.
The point is that present japanese verb conjugation rules and tables are so vague that not even the experts can give a straight answer to
the simple question "how many basic verb conjugations do japanese verbs have?"

The chart I propose helps clarify exactly how many basic conjugations japanese verbs have. In my own experience of close to 20 years with the japanese language and other languages, I'm of the opinion that proficiency in the use of verb conjugations is indispensable in order to attain higher levels of fluency in any given language.

After many years of research, I was able to fit all the pieces of the puzzle together. But, It didn't happen overnight. I spent long hours trying many different options. I checked and doublechecked my conclusions and I also compared them with other charts on the internet , and in japanese grammar books for japanese people, in libraries in Japan,
  and I can say with 100% certainty that the options I propose are 100% accurate.
I have also experimented teaching many foreigners using this system and the results are that students can learn
their japanese verb conjugations in a matter of hours, (watch video)
 

母 stands for all vowels except "e", so, 母+る includes verbs like なる、折る、取る、知る、売る、ETC.
(all of this verbs take a "small っ” in their past and progressive forms)


母+う includes verbs like 会う、言う、洗う、吸う、ETC.

X  = drop this sillable.

”Reversed い+る” verbs include verbs such as  かりる、おりる、いる、みる、 because they are conjugated exactly as the verb たべる;  which is an ”え+る” verb.

”Reversed  え+る” include verbs such as 帰る,喋る、ける、減る、ETC.In other words, these verbs are conjugated like the verbs なる、しる、とる、ETC which are 母+る verbs.

To the irregular verb list (する、来る) I propose to add the verbs 行く and ある because both present an irregularity:
eg. 行く ends in く and for all verbs ending in  ~く the ~く changes to "い" in the ~た~て forms. eg. 書く => 書いた、書いて. 
In the case of the verb 行く the ~く changes into a ”small っ”、行った、行って。Therefore it seems to be an irregular conjugation verb.


In the case of the verb ある、it ends in a vowel + る、same as verbs like なる、はる、ETC,and it shows its irregularity on the negative conjugation where なる would be ならない、はる would be はらない、but ある ends up dropping its first 2 syllables (あら) ない。Thus, this too seems to be an irregularity.

Honorific verbs (おっしゃる、いらっしゃる、くださる、ござる、ETC) are verbs ending in 母+る.
so, if they were regular vebs they’d be conjugated as おっしゃります、くださります、ござります、ETC.
Their irregularity is in the ~ます form. The  ~り~ conjugation changes to ”い”。




Thank you for taking the time to read this, in a nutshell, these are some of the main options I propose in order to help beginer learners learn faster and in a much clearer way.


Please, I'd appreciate any feedback you, Mr. Breen might have on my proposals.
