Concord (Subject-verb Agreement)
Subject-Verb Agreement/Concord Subjects and verbs must AGREE with one another in number (singular or plural). Concord refers in grammar to the agreement between the form of a verb and a subject in a sentence. For example, in "He reads a book," there is concord between the singular form of the verb and the singular pronoun "He." Thus, if a subject is singular, its verb must also be singular; if a subject is plural, its verb must also be plural. In the present tense, nouns and verbs form plurals in opposite ways: nouns : ADD an s/es to the singular form, BUT verbs REMOVE an s/es from the singular form. Example: A student learns writing alphabets at the age 4 or 5. Students learn writing alphabets at the age 4 or 5. Rules If the subject is singular, the verb must be singular too. Example:...
