1. Why is the Tom taller than Sam?
2. Look at the Tom who is running on
the playground.
3. The Tom whom I like is very wealthy.
(Are the sentences grammatical? If not, would you correct them? Thank you.)
Remove the word "the" before "Tom" in sentences 1 and 2, and those sentences will be correct.
#3 is OK.
1. The sentence, "Why is the Tom taller than Sam?" is not grammatically correct. It should be, "Why is Tom taller than Sam?" We do not use the definite article "the" before a first name. "Tom" should also not be capitalized.
2. The sentence, "Look at the Tom who is running on the playground," is grammatically correct. However, it would be clearer if we used the article "the" before "playground." So, the corrected sentence is, "Look at the Tom who is running on the playground."
3. The sentence, "The Tom whom I like is very wealthy," is grammatically correct. However, it is considered more common and natural to use "who" instead of "whom" when referring to a person. So, the corrected sentence is, "The Tom who I like is very wealthy."
