All the programs and applications that can be used to check the spelling of our writing will just precisely check the correct use of vowels and consonants in each and every word, but it will not check if they are correctly used or if they are in the correct collocation within a sentence, that could be revised with a grammar checker.
In the sentence presented above, the two common nouns are <em>lunches and river. </em><em> Maria and Julio </em>are not common nouns but proper nouns<em>. Eat </em>is a verb and <em>side</em> is a noun however, brought and eat are both verbs.
