I think you should go with the advice you found in the grammar book. As I told you before, I might not notice anything wrong with "it" beyond a certain redundancy. As the pronoun is redundant, you can abandon it no matter what your acquaintance advises.I have a real dilemma here. On the one hand, one book (in English) on English grammar advises against using it (or other pronoun) at the end of a sentence. On the other hand, an acquaintance of mine kept persuading me that it is right to use it (or other pronoun) at the end of a sentence.
Isn't the "problem" with this sentence is the use of the indefinite article. If you change the sentence to start with the definite article the instead of an then this is OK..Hello again!
Am I right in thinking that it is correct to say "An apple is ripe enough for me to eat", not "An apple is ripe enough for me to eat it".
Any comments would be appreciated.
