To come/came

K
Kiruきる - Come
Kitaきた - Came

Or so my reading has told me. Anyways also learned kiruきる can also mean 'wear' and kitaきた mean 'wore'. Was wondering if the above are actually right? And if anyone could help me with the:

To come
Coming
Came
Not come

With plain forms, I imagined it would be..

Kiruきる - To come as well as the future will come (which i know they kinda dont really have).
Kiteiruきている - Coming
Kitaきた - Past
Kinaiきない - Negative 'not come'

Cant work out the polite as their never really very concrete in their rules.

Also one more thing why do some taた forms appear as daだ in books? Is it still refering to the past tense or does it mean something else? Because I find taた and daだ in the past verb columns but nothing to tell me why.

Kuru is an irregular verb.
kuru kita konai....

The past forms of "gu", "nu", "bu", "mu" ending verbs are "da".

So just to wrap things up
Normal speech/dictionary form/plain form:
To come = 来る （くる）
Coming = 来てる（きてる）
Came = 来た（きた）
Not come = 来ない（こない）
Didn't come = 来なかった（こなかった）
Polite / -masu form:
To come = 来ます （きます）
Coming = 来てます（きてます）
Came = 来ました（きました）
Not come = 来ません（きません）
Didn't come = 来ませんでした（きませんでした）

Don't get confused when studying 来る and する. They are the only two irregular verbs in Japanese. All the rest are 100% consistent with the rules described in the wikipedia link in the previous post =)
If you don't understand the た vs. だ thing, please don't hesitate to mention so.

Good explanation except "Coming = 来て（い）ます". 来る is an Instantaneous verb.

And 来よう (koyou)....or (kiyou) where I live.
