A verb generally comes at the end of the sentence. Because a subject of a sentence sometimes be omitted, the verb at the end is very important to understand a sentence. Verbs are divided into three groups depending on the style of conjugations.
I should first learn four verbs in the Group 1, with its formal and informal patterns of conjugations. I will make detailed descriptions from my next blog. 
Group 1 ~ U ending verbs Consonant-stem verbs or Godan-doushi (Godan verbs).
au （あう） --- to meet
iku （いく） --- to go
omou （おもう） --- to think
wakaru （わかる） --- to understand
Group 2 ~ Iru and ~ Eru ending verbsVowel-stem-verbs or Ichidan-doushi (Ichidan verbs)
Iru ending verbs
miru （みる） --- to see; to look
kiru （きる） - to wear
Eru ending verbs
taberu （たべる） --- to eat
neru （ねる） --- to sleep
There are some exceptions.
Group 3 Irregular verbsThere are only two irregular verbs, kuru (to come) and suru (to do).
kuru （くる） --- to come
suru （する） --- to do
