In Chinese, sentences are mostly in the SVO (subject-verb-object) word order. So the sentence must be "I eat noodles", not "I noodles eat" or "eat I noodles". In Chinese this is written as 我吃面条. The verb 吃 (pronounced "chī," meaning: "eat") does not change based on the subject "I" or the object "noodles", and likewise the subject 我 (pronounced "wǒ," meaning: "I") and object 面条 (pronounced "miàntiáo," meaning: "noodle/noodles") do not have any special word endings based on its role or number. What is important is that all the words are in the correct order.
