I learnt that to connect several actions (like saying 'and' in English) you have to use the te-form. But when I translated the following using Google Translate: I drink coffee and It gave me this: 私はコーヒーを飲み、(watashi wa kohi wo nomi) Is this an incorrect translation? If not, what form of the verb is 'nomi'? Is it wrong to use the te-form in this case? (like, 私はコーヒーを飲んで)
