If I understand your question correctly, you should always use the gerund form after the verb enjoy. For example: - I enjoy to eat (incorrect) - I enjoy eating (correct) Other examples: admit, avoid, require, mention, imagine, finish, keep, mind, suggest, recall, practise, miss etc. I think these all require the use of gerund after them. With other verbs such as "like" the meaning is unchanged between infinitive and gerund. For example: - I like to eat (correct) - I like eating (correct) Both have the same meaning.

StevenSteven is correct. For grammar like this I recommend: http://www.amazon.com/s/ref=nb_sb_ss_i_0_8?url=search-alias%3Dstripbooks&field-keywords=betty+azar&sprefix=betty+az Your asking shows that you have an intermediate or above level, so study the black book first then go to the blue one. Good Q, keep up the good work.

Hello moon, After 'enjoy' ,which is a verb you will always use a noun to complete the sentence. To enjoy what ? something or someone etc... 'eating' here is a gerund ,which is a verbal noun composed of a verb + ing. " I enjoy eating." " I enjoy the food." All nouns in different forms! You will never use an infinitive after 'enjoy' . As a rule you don't use 2 infinitive verbs subsequently, unless the first main verb is an auxiliary one such " do, can, must..." " I do like you." " I do enjoy eating." " I must tell you."
