Comments for 泳ぐ

During the last months I have been studying and memorizing verbal, adjectival, nouns, etc and also to learn kanjis...

looking for the emotion when challenges are improved, I have been trying to read articles an newspapers. magazines and even in your examples, but just realized I am too far to understand japanese because I found the "polite forms" i have studied until now, do not appear often but so called Te form, or Tai form .. and other conjugations forms I had no considered/studied...

well... I will start coming back on each learnt verb to also learn these new forms...

but.... I don't find when is expected to be used Tai form or Te form....could you guide me to some lesson or book where I can understand about uses of differentes ones?

regards

Trying to understand the way to make sentences in Polite form and plain form, I have taken just a sentence and following my logic made following table...

Could you just say me if that is correct? may I follow same logic for all verbs?

to make a sentence in plain form just change verbal  but basic structure keep the same?

Sentence in english:      I read newspaper every day.

Polite Form:   
Present Indicative                読みます                yomimasu                   私は毎日新聞を読みます。
Present Indicative Negative 読みません            yomimasen                 私は毎日新聞を読みません。
Past Indicative                     読みました             yomimashita                私は毎日新聞を読みました。
Past Indicative Negative      読みませんでした  yomimasendeshita      私は毎日新聞を読みませんでした。
Presumptive                        読みましょう           yomimashou                私は毎日新聞を読みましょう。
 

Plain Form:   
Present Indicative                    読む                 yomu                          私は毎日新聞を読む。
Present Indicative Negative     読まない          yomanai                     私は毎日新聞を読みまない。
Past Indicative                          読んだ             yonda                        私は毎日新聞を読んだ。
