As subjects, the following indeterminate pronouns ALWAYS take singular verbs. Look at them carefully. 8. Names such as scissors, tweezers, pants and scissors require plural abraminations. (These things are done in two parts.) 2. Subsidiary sentences between the subject and the verb shall have no influence on their concordance. However, there are some guidelines for deciding which form of verb (singular or plural) should be used with one of these nouns as a subject in a sentence. Note: The word dollar is a special case. When we talk about a sum of money, we need a singular, but if we refer to the dollars themselves, a plural abrasing is necessary. Subjects and verbs must correspond in number (singular or plural). So, if a subject is singular, its verb must also be singular; If a subject is plural, its verb must also be plural.
This is the basic idea of subject-verb concordance. .
