Should we use "to" when recommending something? So should this sentence be "Do you recommend people TO eat Durian"?
No, the word "to" isn't really necessary when recommending something. You can add "to" in the sentence, but it's not always needed. It really just depends on the structure of the sentence. Here are some examples of recommending others to something with and without the word "to." Ex: I recommend that you eat pineapple. Ex: It is recommended that you go to college for certain careers. Ex: Do you recommend that others try eating more vegetables?
