Question about first, second, third, fourth. Please help! Can I use the format "First is xxx( noun) /Second is xxx (noun)" to write a sentence?For example: I love Mary because of three reasons. First is physical appearance, she has big eyes..... Second is personal character, she is a nice person.... If the format is grammatically incorrect, which words/phrases can I use to replace it except the phrase "in terms of". Thanks a lot!
